If you’re looking to build strength and increase muscle mass, your exercise routine needs to include moves that work your fast-twitch muscles. These muscle fibers are responsible for muscle definition and generate power and strength in the body. They come into play when our slow-twitch muscles tire, but are also activated with explosive exercises like sprints, jumps and heavy weight training.
Coach Josh from Graham Wellness shows us how to use a medicine ball toss to strengthen the fast-twitch muscles in the chest, shoulders and arms. The goal is to push the ball high into the air by generating explosive power through the chest. Don’t have a medicine ball? Coach Josh takes us through the same routine using a dumbbell and kettlebell. Just make sure to hold onto that weight!
