Doing a back flip can help stretch the back and tone up the stomach. The lean backstretch to do a back flip can be achieved in a standing position without following through the complete bend and flip.
Standing up straight and leaning to the left and right offer stretch, loosening the flexibility of the hips so that you can prepare for the back flip stretch. Standing and leaning forward is another exercise to stretch and loosen back flexibility.
The backstretch is fairly simple. Stand up straight and slowly lean back. When you lean, lean far enough that you won’t lose your balance and fall but far enough that you can feel the stretch. You don’t have to lean very far. When you feel the stretch slowly lean forward into your original starting position.
The backstretch can be done as a standing stomach crunch the only modification you’ll need to do is once you slowly lean back pull in and hold your stomach just like you would if you were in a lying-sitting position and doing a crunch when returning forward.
You can lean against a wall and alternate standing leg lifts to further work the stomach. Lift each leg up to where the knee is straight before lowering the leg. Hold the leg lift to the count of ten if you can to add to the degree of difficulty.
Another simple backstretch that works the shoulders and arms to is done by holding both arms out straight to the side with the hands flat or by holding arms out straight and bending the arms up straight with the hands flat. In either position thrust the arms forward and back in repetitive rapid motion. Do not flap the arms. This exercise can be performed sitting or standing.
If you are in a sitting position you can pull in and hold the stomach while you alternate lifting one leg up enough to feel a pull in the upper portion of the leg above the knee and in the stomach. Hold each leg lift to add to the degree of difficulty. While alternating sit down leg lifts hold on to the armrests to support your self.
Exercises may not be advised if you have back pain or an injury to the back. Ask a professional before attempting to do any exercise that may inflict pain or injury to the back to avoid additional pain or injury.
