Is the 1/4" mat shock absorbent, as far as if I am using it as an exercise floor to do any jumping movements (jumping rope, high knees, box jumps, long jumps, squat/lunge jumps)? I will be laying it over a concrete garage floor.

Our standard rubber flooring can be used for jump training, but is not the most shock-absorbent or the best floor for this type of training. We do offer a wide range of impact flooring that would be perfect for this type of training and are some of the most shock-absorbent floors on the market today. You can find all of these floors on Impact Flooring list page.
