Do you perform the same exercises every week? If your progression has stalled then it’s time to shock your body.
Aim for a training response from each workout by using the method of rotating exercises frequently. Even though there are only a few movement patterns our bodies can move in there are many alternatives to the exercises you have probably been using.
It is possible to get a different response by using different tools and the way you perform exercises.
The bottom line is the more you change your exercises the less chance your body will adapt to what you are doing resulting in a tougher workout with better results.
