A good all-body workout can be achieved by using your own body weight.  You can build strength, balance and flexibility, which can build a strong core.  The Pikes Peak Push-Up is such a move.  

You place your body into a downward dog position; in other words, your hands and toes are on the floor, with your body forming a triangle or a peak.  

Automatically your hamstrings and spine begin to stretch. You create upper body and core strength, and balance when you perform the move. The Pike Peak Push-Up is a challenging move, and it is recommended for those who want to go the next level in their fitness performance. 

• Come into a downward dog position. 
• Place feet hip-distance apart.
• Engage the abdominals and maintain straight legs, depending on your hamstring flexibility.
• Place the hands wider than your shoulders.
• Come up on your toes, lifting the heels off the floor.
• Notice how your glutes lift higher toward the ceiling.
• Look between your hands.
• Maintain a long spine, strong abs and legs.
• Bend your elbows to a 90-degree angle.
• Don’t allow your face/nose to hit the floor.
• Then straighten the arms.  That’s one pike peak push-up.
• Perform as many as you can.
