Kern Alexander, Co-founder of Leading Edge Personal Trainers shares the top 6 chest exercises to help you strengthen muscles as well as build mass and how these exercises are beneficial to both men and women. With each exercise, you will learn how to perform the movement, the purpose of the exercise and what equipment is needed. The number of reps you do will depend on whether your priority is building muscle or becoming stronger. To build muscle, 10-15 reps would be ideal, but to build strength, about 4 or 5 reps with a heavier load would be better.
