Lie on your stomach and place your forearms on the ground in a way that your Upper arms are placed directly under your shoulders (at this point only your forearms and toes should be on the ground & the entire body should be in a straight line).
2. Elevate your body by extending your arms and squeezing your triceps. Make sure to keep your entire body (from shoulders to Knees-heels) in a straight line.
3. Bend your elbows and slowly return to the starting position.
