I always begin by saying this is my favorite grind. I will start my own personal challenge on the 1st of December .
Do one TGU on the 1st , 2 on the 2nd, etc. Start on the floor to upright position and down again completes your 1st one !
Take your measurements and take a mental note of how strong you are now and how much more you will be after the challenge.
Remember this can be a body weight only exercise .Use a shoe balanced on your fist to keep you in aline .
Good Luck
