XTREME PRO™ Xmount

I love this! It really challenges you and engages your core more than any plank I could do or HIIT workout alone. The X Pro is a great alternative for weights, at least for me. The only thing I would caution is to make sure you hang this on a door that closes the same direction of your pulling. Meaning if you're pulling the X Pro toward you with a workout, that door should be a door that also pulls closed. It works okay on doors that open toward you, but I have better piece of mind that I'm not just relying on a thin lock bar
