Hey,
Never heard of this exercise before - I would try it now only im just home from my 2nd ever body combat class.
Glad u shared this as I will do it tomorrow and then as I progress with my new fitness regime and also im expecting my slendertone to arrive this week - it will be a great way to measure my fitness every week and see how i am improving!
Im weak as fook... i dare say i will last a minute the first time! lol
