Muscle Building Strategies
Increase repetitions
Increase volume by adding more sets
Increase range of motion while lifting the same weight
Increase time under tension by manipulating lifting tempo (concentrics, eccentrics, 1.5 reps, isometric holds, etc.)
Increase training density by completing more reps in the same amount of time
Lift the same weight for the same amount of sets and reps while resting less between sets
Lift the same weight with greater speed, power and acceleration
Increase training frequency (how many times you train a particular muscle group each week which can help increase total training volume)
