Viva La Glory Fitness:
V LEG LIFTS: Start out laying straight on the ground, holding the medicine ball above your shoulders and chest. With straight legs, hover your feet a few inches above the ground. Keeping your arms still, raise your straight legs up to the right of the medicine ball; bring legs back down towards ground. Repeat on the left side; this is one rep. Complete ten or more reps, increasing as you get stronger. This one is particularly challenging!
