TONE IT

This little toner is so great for abs, back and shoulders!
I'm using a 15# DB here, but definitely use your weight sparingly! If you haven't lifted in awhile, use something very light.
Advanced version: keep both legs up in a row boat and do 8-10 presses each arm.
Moderate version: keep just one leg down
Do this move alternating with some kind of leg exercise, maybe walking lunges!!

Be sure to lean back and pull your abs in!
