If you are having troubles improving acceleration in your game, look no further. The now popular prowler can be used to improve just that.
The great thing about using the prowler is that it very easy to use and does not require much skill to use. All you need is a prowler, some plates (if desired), and some space to run up and down, preferably indoors or an area where there isn't too much traffic.
Squats: Front or back squats will not only strengthen the legs but also your upper back and help you gain some lean mass. Getting stronger in the squats can help with the production of force applied to the ground while sprinting.
