A product for people tonics

A robust product with a broad wheel for stability but not too large to be still in balance
The ride is good, there is no action that hinders which made it really works on the pace we impose
The only limitation being that it is only one year Is proposed in the manual with two variants

The exercises allow Work the abs and the muscles of his isometrically sheathing (keep posture) or eccentric (muscle resistance action)

My opinion of unsportsmanlike who delivered 4 months ago and who has a bad back that the starting posture is impossible for me to take (too painful)
In contrast to my spouse, sportier, he finds an original way to regain sheathing and abs and muscles work in depth with a suitable program

A more compact and transportable unit on vacation

I recommend this product for people who are a minimum and tonics that do not suffer from back or knee problems
