Check out my training log in the Sponsored Lifters Section for my review of the APEX. It spans over several weeks. I have been using the shirt, both the double and triple ply, off of 1, 2 , and 3 boards. So far I love the shirt. It is much easier to use than the shirts I was previously using and I'm learning that you can crank it in the same ways with similar effects, neck down, sleeves tucked and twisted. They all help. Check out the vids.
