10. Wall Abs
Stand about 12 inches from a wall, facing away, with knees slightly bent. Extending your hips and spine, reach overhead with hands clasped into fists. Arch your back slightly and lean backward—lifting one leg out in front of you—to touch the wall. Try to control the movement as you slowly return to an upright position with both feet on the ground. Complete 10 to 15 reps, alternating legs.
11. Hamstring Stretch
Prop your foot up on a bench or another object about 2 feet high. Flex your foot and reach with your opposite hand across your shin. Pulse in and out of this stretch 5 to 10 times, trying to stretch a little bit farther each time. Repeat on opposite side.
