This is a classic, and I know you’ve done them before, but when done correctly, they’re an effective way to strengthen a lot of muscle groups (basically your entire core and upper body) all at once. I like exercises that involve 50 percent or more of your body’s muscles, because they’re a great use of time and super-functional. With push-ups, you’ll activate all core muscles, and your shoulders, hips, and everything else down to your shins, since you’re positioned on your toes.
BENEFITS:
For starters, you’ll increase bone density in your arms and wrist bones. Did you know that it takes approximately 1/10 of the force needed to break a bone to make it stronger? Ask yourself, if you trip while running, will the bones in your hands, wrists, and arms resist a break? Push-ups help prevent you from ever actually having to discover the answer to that question.
HOW TO:
1
.
Lie face down on the floor with your hands directly under your shoulders, your abs engaged, your legs together and extended behind you, toes tucked under.
2
.
Press into your palms and lift your body straight up, keeping your shoulders down and trying to maintain a straight line throughout; lower back to start and repeat.
3
.
Begin with 5 to 10 reps, but do as many as possible. If you need to modify this and go down on your knees, that’s fine. Remember, just by attempting this exercise you are making progress.
