Work those abs with a full contact twist exercise on a MA1 extreme core trainer. A full contact twist develops the capacity to transfer power from the legs, into your core and out through your arms. Also great for beginners looking to start deadlifting and squats, the extreme core trainer removes the issues with balance and comfort of bar positioning. The core trainer also allows you to lean into the weight while squatting or away during a deadlift for a bit more leeway. Forget building your core muscles on the floor and get up onto your feet with an extreme core trainer for real world strength that will benefit everyday life.
