Fast Abs machine is junk!! The intensity on it is too low!! I've tried several of them...and believe it or not Abtronic has the highest adjustable intensity levels than the rest!!
Its all bullshit...great ploy to make money...wish i thought of it...its kinda like spot injections...for example people swear by spot injections claiming some AS helps localized growth..But the truth is if it did wouldn’t we all be walking around with really big butts...as a college athlete every time you get a cramp in your calf or hurt your quad our trainers hook us up to electric Stem machine..Which is the same idea as fast abs..except its a shit load stronger...well this past season I spent about 2hour every day for 3months with this treatment on my quads and calves and never ever saw them grow in anyway...now with that intensity and amount of time I spent doing treatment I never noticed any increase of size...so no fast abs is a joke....g..
