Have your weights ready. I used 15's, a 12, an 8, both 5's, both 3's. The single arm tricep wasn't working for me so I upped the weight and used both hands for both the L and R set. I found that to work better for me but it was super hard to go into the up down planks after that! The 60 second plank with arm circles was VERY challenging. On the last set, I fell out of it w. 22 secs left but jumped back in with 13 secs left. It was hard! I did a 10 min cardio before this so I got a great workout in. Thanks so much.
