3) High Five Lie on your back on the bed and plant your feet flat. Bridge your hips up so your butt is raised. Reach up with one arm alternately as if you’re giving a high five. Keep your hips elevated.
4) Plank-Up Get into the plank position (as described in the seagull). From there, move your arms to get into the top of a push-up position. Go back down to the plank and continue for 30 seconds.
5) Alternating Knee Drive Get into push-up position and raise one knee at a time up to your chest and back. 6) Single-Leg Squat Stand on one leg, brace your abs, and lower yourself into a squat, going as deeply as you can.
