I love this series of exercises, it's a great strength routine that you can knock out in about 25 or 30 mins. I like the fact that no equipment is needed so it's really easy to do when I'm not at home.
My personal goal is to try and complete at least 3 sets.
Do you have a series of exercises you fall back on when short on time or away from home? Would love to hear about your favorite routines!
