It's good to get off the floor every so often to work your core in a new way!
Try my standing abs routine this week to tone up your entire mid section. We use body weight + small hand weights for resistance. Focus on balance, control + form to get the most out of each station. We're working with the timer to stay on track, and avoid super long rest periods.
Repeat this 2-3x, three times a week to see max results!
