Tweetcardio only yesterday and today well cardio with a twist:
30 mins step mil
5 min warmup
10 min stepping up on toes for a hard contraction
12 min contracting the ham and glute each step
3 min normal stepping.
give it a try next time you do cardio cause it will wind you faster than running and hurts like a *****. honing in them hams and glutes going to look like a zebra and then some this upcoming season
