Using Intensity, Frequency and Volume you can see some serious gains without even changing an exercise. Using these three variables you can continue to progress and keep building muscle!
Spend more time under tension and what your gains increase! Focus on execution, movement quality and taking your time for muscle growth!
If you want to grow more muscle, start training with Range of Motion in mind. Sink deeper in your squats, lunges and hinge based movements! You'll grow more muscle and increase the integrity of your joints with proper execution!
