I exercised again today! Only 50 minutes this time, but that is more than fine with me as I am sore from yesterday.
I did the first video twice (ouch!), the second video once (thought I didn't do the last couple of minutes as my brother rocked up at my house), and the last video once - yep, it's the back one from yesterday! I made my brother do the back one with me and he just managed to make it through!
