To incorporate more of your office furniture, Bowling likes the desk Russian twist, which also targets all the major core muscle groups, but primarily the obliques.
You'll need to:
- Sit on your desk with your knees over the edge.
- Lean back to a 45-degree angle, or as far as you can while maintaining a neutral spine (no arch).
- Rotate your torso and touch the desk beside your right hip with both hands.
- Repeat to the left.
- Begin with 8 to 10 repetitions to each side, two to three sets.
Proper technique, like most core exercises, is essential in the Russian Twist. If you can get to that 45-degree angle without arching your back, great. If not, don't. The moment your back begins to arch, you need to come forward to a point where you can hold that angle.
