I like how it starts out slow. Not expecting you even be able to do one lol. But seriously its really good training. I started out barely able to do 5 at proper form. Up to about 12 without cheating. And the proper form is really important. I talked to a trainer realized I wasnt using proper form and actually had go back a level lol.
