I have never, ever been able to do this exercise. I have tried so many times and it ended in frustration. Don't laugh - but I could never keep from tipping forward. I can see the benefit of this exercise and was always pretty bummed I couldn't get it right.
Seems to build some serious quad size, at least for those I see do them on a continual basis.

"We deceive ourselves when we fancy that only weakness needs support. Strength needs it far more."
The success a person achieved in life after life is over is not measured by the material items, wealth or land they acquire. But in the lives they have touched in a positive way and the people who remember them with a fondness and a smile or a tear that they are no longer.
