This move is one of my favorite burnouts! It uses my red versa loop (amazon.com from Power System).
If you cannot get into the knee plank version I show here, you can press your hips to the back wall so you are more table-top.
The pattern you use is up to you but keep the band tight at all times. It’s sloppy to let it get loosey goosey in the middle. You will receive the benefit of the time>under tension style of training.
Many clients use these bands but miss on the great benefits because they let the band slack.
My brides and competitors love this one. You know what? If your arms are tight… you look young! No droop allowed!!
See how you do!! Good luck
