@lensfitapp: Most people rush the eccentric and miss 90% of the gains. Lower the weight for 3 full seconds, then drive up with control — this time under tension builds way more muscle than slamming reps. Avoid bouncing at the bottom and using momentum to cheat the movement. Keep your core braced and your reps slow enough that you actually feel the target muscle working. Save this for your next session.#strengthtraining #gymtips #progressiveoverload #musclebuilding #liftheavy
