Strength Training
What is autoregulation in training?
Four methods are: increasing weight (add 2.5–5 lbs), increasing reps within a set, adding sets to increase total volume, and decreasing rest intervals between sets. Tempo changes and range of motion improvements also count.
A caloric surplus means consuming more calories than you expend. A moderate surplus of 250–500 calories/day provides the energy needed to build new muscle tissue while minimizing excessive fat gain.
Autoregulation adjusts training load based on daily performance readiness rather than fixed percentages. Methods include RPE/RIR-based loading, velocity-based training, and AMRAP sets, allowing optimal stimulus even on good or bad days.
MRV is the highest amount of training volume from which you can still recover. Exceeding MRV leads to overtraining, accumulated fatigue, and regression. It varies by individual, muscle group, and training phase.
Strength Training
What is progressive overload?
DOMS (Delayed Onset Muscle Soreness) is soreness that peaks 24–72 hours after training, caused by eccentric muscle damage. It is not a reliable indicator of a productive workout; muscles can grow without significant soreness.
Progressive overload is the gradual increase of stress placed on the body during training. This can be achieved by increasing weight, reps, sets, or decreasing rest periods, and is the primary driver of strength and muscle gains.
Four methods are: increasing weight (add 2.5–5 lbs), increasing reps within a set, adding sets to increase total volume, and decreasing rest intervals between sets. Tempo changes and range of motion improvements also count.
RIR (Reps in Reserve) estimates how many more reps you could perform before failure. It directly maps to RPE: RPE 10 = 0 RIR, RPE 9 = 1 RIR, RPE 8 = 2 RIR, and so on.
Strength Training
What is the leg press and what muscles does it target?
The overhead press involves pressing a barbell or dumbbells from shoulder height to full lockout overhead. It primarily targets the anterior and lateral deltoids, triceps, and upper chest, with core muscles stabilizing the torso.
The leg press is a machine-based compound exercise targeting the quads, hamstrings, and glutes. Foot placement variations (high, low, wide, narrow) shift emphasis between muscle groups. It is a safer alternative to squats for some lifters.
A full-body split trains all major muscle groups in every session, usually 3 days per week. It is ideal for beginners because high frequency per muscle group accelerates motor learning and strength gains.
Three bench press variations are the incline bench press (targets upper chest), close-grip bench press (emphasizes triceps), and dumbbell bench press (allows greater range of motion and independent arm work).
Strength Training
What is proper breathing technique during heavy lifts?
Inhale and brace before the eccentric (lowering) phase, hold the breath through the sticking point, and exhale during the concentric (lifting) phase or at lockout. This maintains intra-abdominal pressure and spinal stability.
Most intermediate to advanced lifters benefit from a deload every 4–8 weeks , depending on training intensity, volume, and individual recovery capacity. Beginners typically need deloads less frequently due to lower absolute loads.
An RPE 8 means you completed your set and feel you could have performed 2 more reps before failure. This level of effort is commonly used for productive strength and hypertrophy training while managing fatigue.
A compound exercise works multiple joints and muscle groups simultaneously (e.g., squat, bench press), while an isolation exercise targets a single joint and muscle group (e.g., bicep curl, leg extension). Compound movements allow heavier loads and greater hormonal response.
Strength Training
What is the optimal rep range for muscular endurance?
Unilateral training involves working one limb at a time (e.g., single-leg squat, single-arm row). It corrects muscle imbalances, improves stability, and prevents the stronger side from compensating for the weaker side.
For muscular endurance , training with 15–25+ reps at 40–60% 1RM is most effective. This improves the muscle's ability to sustain repeated contractions and enhances capillary density and mitochondrial function.
Time under tension is the total time a muscle is under load during a set. Controlling tempo (e.g., 3-second eccentric, 1-second pause, 2-second concentric) increases TUT, which can enhance hypertrophy by increasing metabolic stress.
In a conventional deadlift the feet are hip-width and hands outside the knees, emphasizing the back and hamstrings. In a sumo deadlift the feet are wide with hands inside the knees, placing more emphasis on the quads and adductors with a more upright torso.
Strength Training
How can you prevent lower back injuries during training?
Undulating periodization varies intensity and volume within a single week (e.g., Monday: heavy 5×5, Wednesday: moderate 4×8, Friday: light 3×12). This frequent variation can prevent accommodation and maintain diverse training adaptations.
Prevent lower-back injuries by maintaining a neutral spine , bracing the core (Valsalva maneuver), using appropriate loads, and strengthening the core and posterior chain. Avoid rounding the back during deadlifts, rows, and squats.
A training max is a percentage of your true 1RM (often 85–90%) used for programming purposes. Training below your true max allows sustainable progression and reduces injury risk while still providing an effective training stimulus.
Dietary fats support hormone production (including testosterone), cell membrane integrity, and absorption of fat-soluble vitamins (A, D, E, K). A minimum of 0.5–1 g/kg/day is generally recommended for health and performance.
Strength Training
What is the difference between a pull-up and a chin-up?
A pull-up uses an overhand (pronated) grip and emphasizes the lats and upper back. A chin-up uses an underhand (supinated) grip and recruits more bicep involvement, often making it slightly easier for beginners.
The six major muscle groups are chest (pectorals), back (latissimus dorsi, trapezius, rhomboids), shoulders (deltoids), arms (biceps, triceps), legs (quadriceps, hamstrings, glutes, calves), and core (abdominals, obliques, erector spinae).
A spotter is someone who assists during heavy lifts to prevent injury if you fail a rep. Spotters are essential for exercises like the bench press and back squat when training at high intensities (RPE 9–10).
The Brzycki formula is: 1RM = weight × (36 / (37 − reps)). It is most accurate for sets of 10 reps or fewer and tends to give slightly lower estimates than the Epley formula at higher rep ranges.
Strength Training
What is periodization in strength training?
A rep (repetition) is one complete movement of an exercise through its full range of motion. For example, lowering and pressing the bar once on bench press is one rep.
The conventional deadlift primarily works the posterior chain : hamstrings, glutes, and erector spinae. It also heavily involves the quadriceps, lats, traps, and forearm grip muscles.
Periodization is the systematic planning of training into phases (e.g., hypertrophy, strength, peaking) over weeks or months. It prevents plateaus, manages fatigue, and optimizes performance for specific goals.
A superset pairs two exercises performed back-to-back with no rest between them. They can target the same muscle group (compound set) or opposing muscles (antagonist superset, e.g., bicep curl + tricep extension) to save time and increase intensity.
Strength Training
What is a common mistake during the overhead press?
Progressive overload is the gradual increase of stress placed on the body during training. This can be achieved by increasing weight, reps, sets, or decreasing rest periods, and is the primary driver of strength and muscle gains.
Unilateral training involves working one limb at a time (e.g., single-leg squat, single-arm row). It corrects muscle imbalances, improves stability, and prevents the stronger side from compensating for the weaker side.
Three common squat variations are the front squat (barbell on front delts), goblet squat (holding a dumbbell at chest), and Bulgarian split squat (rear foot elevated). Each shifts emphasis to different parts of the legs and core.
A common mistake is excessive lower-back arching to compensate for weak shoulders, which places stress on the lumbar spine. Bracing the core, squeezing the glutes, and using an appropriate weight help maintain proper form.
Strength Training
What is the posterior chain?
A set is a group of consecutive repetitions performed without rest. For example, doing 10 push-ups without stopping is one set of 10 reps.
The posterior chain includes all muscles on the back side of the body: hamstrings, glutes, erector spinae, lats, and calves. Strengthening it is critical for athletic performance, posture, and injury prevention.
Protein powder (whey, casein, plant-based) is a convenient supplement but not essential. It helps reach daily protein targets when whole-food intake is insufficient. Whole foods should form the foundation of your nutrition.
For hypertrophy (8–12 reps at moderate intensity), rest 60–90 seconds between sets. Shorter rest periods maintain metabolic stress, which is a key driver of muscle growth.
Strength Training
What is the eccentric phase of a lift?
Muscular strength is the maximum force a muscle can produce in a single effort (trained with heavy loads, 1–5 reps). Muscular endurance is the ability to sustain repeated contractions over time (trained with lighter loads, 15+ reps).
The five points of contact are: head , upper back/shoulders , and glutes on the bench, plus both feet flat on the floor. This creates a stable base and allows leg drive to assist the press.
The posterior chain includes all muscles on the back side of the body: hamstrings, glutes, erector spinae, lats, and calves. Strengthening it is critical for athletic performance, posture, and injury prevention.
The eccentric phase is the lowering portion of a lift where the muscle lengthens under load (e.g., lowering the bar to the chest in bench press). Eccentric training causes more muscle damage and is a strong stimulus for hypertrophy.
Strength Training
How can you train through a sticking point?
The RPE (Rating of Perceived Exertion) scale rates effort from 1–10, where RPE 10 means maximum effort (no more reps possible) and RPE 7 means about 3 reps left in reserve. It helps autoregulate training intensity based on daily readiness.
The "bro split" assigns one muscle group per day (e.g., Monday: chest, Tuesday: back, Wednesday: shoulders). While popular, it typically trains each muscle only once per week, which may be suboptimal for natural lifters compared to higher-frequency splits.
You can train through sticking points using pause reps (holding at the weak position), pin squats/presses (starting from the sticking point), tempo work , and accessory exercises that target the muscles weakest at that range.
Dietary fats support hormone production (including testosterone), cell membrane integrity, and absorption of fat-soluble vitamins (A, D, E, K). A minimum of 0.5–1 g/kg/day is generally recommended for health and performance.
Strength Training
What are the six major muscle groups of the body?
The six major muscle groups are chest (pectorals), back (latissimus dorsi, trapezius, rhomboids), shoulders (deltoids), arms (biceps, triceps), legs (quadriceps, hamstrings, glutes, calves), and core (abdominals, obliques, erector spinae).
The face pull targets the rear deltoids, rhomboids, and external rotators of the shoulder. It helps counteract the internal rotation and anterior dominance caused by heavy pressing, reducing shoulder injury risk.
GPP is a broad base of fitness including cardiovascular endurance, muscular endurance, flexibility, and coordination. A strong GPP foundation supports specific strength training goals and improves overall work capacity.
Dietary fats support hormone production (including testosterone), cell membrane integrity, and absorption of fat-soluble vitamins (A, D, E, K). A minimum of 0.5–1 g/kg/day is generally recommended for health and performance.
Strength Training
What are supersets?
Tendinitis is inflammation of a tendon, often caused by repetitive stress or rapid load increases. Prevention includes progressive overload, adequate warm-ups, proper form, balanced programming, and sufficient recovery time between sessions.
Periodization is the systematic planning of training into phases (e.g., hypertrophy, strength, peaking) over weeks or months. It prevents plateaus, manages fatigue, and optimizes performance for specific goals.
Protein powder (whey, casein, plant-based) is a convenient supplement but not essential. It helps reach daily protein targets when whole-food intake is insufficient. Whole foods should form the foundation of your nutrition.

Strength Training
What is the role of the core in heavy lifts?
A compound exercise works multiple joints and muscle groups simultaneously (e.g., squat, bench press), while an isolation exercise targets a single joint and muscle group (e.g., bicep curl, leg extension). Compound movements allow heavier loads and greater hormonal response.
The core acts as a stabilizer, transferring force between the upper and lower body and protecting the spine. Bracing the core (creating 360° of intra-abdominal pressure) is essential during squats, deadlifts, overhead presses, and rows.
A common cause is excessive elbow flare (arms at 90° to the torso), which places stress on the shoulder joint. Tucking the elbows to about 45–75° and retracting the scapulae helps protect the shoulders.
A Pendlay row starts each rep from the floor with an explosive pull and a more horizontal torso. A bent-over row keeps the bar in the air between reps and allows a slightly higher torso angle, maintaining constant tension.
Strength Training
What is the push/pull/legs (PPL) training split?
Start from a dead hang with palms facing away, hands just wider than shoulder-width. Pull your body up by driving elbows down and back until your chin clears the bar, then lower with control. Avoid excessive kipping or swinging.
Periodization is the systematic planning of training into phases (e.g., hypertrophy, strength, peaking) over weeks or months. It prevents plateaus, manages fatigue, and optimizes performance for specific goals.
RIR (Reps in Reserve) estimates how many more reps you could perform before failure. It directly maps to RPE: RPE 10 = 0 RIR, RPE 9 = 1 RIR, RPE 8 = 2 RIR, and so on.
PPL divides training into three sessions: Push (chest, shoulders, triceps), Pull (back, biceps, rear delts), and Legs (quads, hamstrings, glutes, calves). It is typically run twice per week for six training days.
Strength Training
What is an AMRAP set?
The cue "chest up, hips back" helps engage the lats and prevent rounding. Thinking of "pushing the floor away" rather than pulling the bar also promotes proper hip hinge mechanics.
The conventional deadlift primarily works the posterior chain : hamstrings, glutes, and erector spinae. It also heavily involves the quadriceps, lats, traps, and forearm grip muscles.
AMRAP (As Many Reps As Possible) means performing as many quality reps as possible with a given weight, typically on the last set. It is used to gauge progress, push intensity, and auto-regulate volume.
Training intensity refers to the load used relative to your one-rep max (1RM). It is expressed as a percentage (e.g., 80% of 1RM). Higher intensity means heavier weight and fewer reps per set.
Strength Training
What is a caloric surplus and why is it used for muscle gain?
A caloric surplus means consuming more calories than you expend. A moderate surplus of 250–500 calories/day provides the energy needed to build new muscle tissue while minimizing excessive fat gain.
The interference effect occurs when endurance training blunts strength and hypertrophy adaptations due to conflicting molecular signaling pathways (AMPK vs. mTOR). Separating sessions by 6+ hours and prioritizing the primary goal helps minimize this.
A Pendlay row starts each rep from the floor with an explosive pull and a more horizontal torso. A bent-over row keeps the bar in the air between reps and allows a slightly higher torso angle, maintaining constant tension.
The six major muscle groups are chest (pectorals), back (latissimus dorsi, trapezius, rhomboids), shoulders (deltoids), arms (biceps, triceps), legs (quadriceps, hamstrings, glutes, calves), and core (abdominals, obliques, erector spinae).
Strength Training
What is tendinitis and how is it commonly prevented?
A good squat warm-up includes 5 minutes of light cardio (cycling, rowing), followed by dynamic stretches (leg swings, hip circles), bodyweight squats, and ramping warm-up sets (empty bar, 50%, 70%, 85% of working weight).
Tendinitis is inflammation of a tendon, often caused by repetitive stress or rapid load increases. Prevention includes progressive overload, adequate warm-ups, proper form, balanced programming, and sufficient recovery time between sessions.
A pull-up uses an overhand (pronated) grip and emphasizes the lats and upper back. A chin-up uses an underhand (supinated) grip and recruits more bicep involvement, often making it slightly easier for beginners.

Strength Training
How much rest should you take between sets for hypertrophy?
MRV is the highest amount of training volume from which you can still recover. Exceeding MRV leads to overtraining, accumulated fatigue, and regression. It varies by individual, muscle group, and training phase.
The six major muscle groups are chest (pectorals), back (latissimus dorsi, trapezius, rhomboids), shoulders (deltoids), arms (biceps, triceps), legs (quadriceps, hamstrings, glutes, calves), and core (abdominals, obliques, erector spinae).
Three common squat variations are the front squat (barbell on front delts), goblet squat (holding a dumbbell at chest), and Bulgarian split squat (rear foot elevated). Each shifts emphasis to different parts of the legs and core.
For hypertrophy (8–12 reps at moderate intensity), rest 60–90 seconds between sets. Shorter rest periods maintain metabolic stress, which is a key driver of muscle growth.
Strength Training
What is the optimal rep range for hypertrophy?
Three compound lower-body exercises are the back squat , deadlift , and lunge . Each engages the quadriceps, hamstrings, glutes, and core to varying degrees.
For hypertrophy , the traditional optimal range is 6–12 reps at 65–80% 1RM. However, recent research shows muscle growth occurs across a wide rep range (5–30) as long as sets are taken close to failure.
A full-body split trains all major muscle groups in every session, usually 3 days per week. It is ideal for beginners because high frequency per muscle group accelerates motor learning and strength gains.
