- used by gymnasts to practice the "hollow" position, this ab exercise is very difficult when done correctly
- maintain a hollow position, your back rounded and rock back and forth on your spine
- you should be able to do at least 15 pull ups and 15 dips before even attempting this movement
- a "false grip" is required
- practice by coming up as high as possible in your pull ups and as low as possible in your dips
- the closer your hands are to the wall the harder these get.
- get your forehead down to the ground
- try on parallettes for added challenge
- lower yourself with your arms outstretched in front of you.
- don't go so low that you allow your back to arch
Work on increasing the height of your pull ups up to your chest and increasing the depth of your dips, getting your armpits down to the height of your hands. Key is also in the "false grip".
