This 4-Week Challenge Will Help You Finally Conquer Push-Ups

• Begin lying on your back. Lift your legs and arms up so they are extended toward the ceiling, then lift your upper back off the floor, reaching your hands toward your feet. Pull your core in toward your spine and keep your neck straight; avoid straining forward.
• Slowly lower your legs toward the floor while simultaneously reaching your arms overhead. Keep your shoulders off the mat and your lower back pressed into the ground.
• Lift your legs and and arms to return to the starting position. This completes one rep.
• Complete 15 reps.

Run through week two's circuit a total of four times. Complete this workout on three non-consecutive days this week.
