Hey,
I's curious to know if any of you have or have experience with the gymnic 120 CM exercise ball?
Does it really expand to 120 centimeters?
When not inflated almost to bursting but still to rated capacity, how firm is it underneath you?
How does it feel to sit on it?
There's one on amazon that I've been eyeing for a very long while but I thought I'd check with you guys and gals who may own one first.
Thanks!
