Without non-slip pad is slipping off because the blue ball-bottom is smooth and slips hinundher on flooring or carpet, hence there danger of falling.
If the plastic bottom slip roughened (eg with my balance board), then the risk would be it sliding with the whole thing, far less.
But so: everything first clear away within what could be injured in a possible slippage (eg table edges), then drunterlegen a non-slip pad (I have a piece of foam taken).
Etc. First, near the wall ascend, because as you can first hold or support something.
At the height, (which is only recommended for advanced users anyway), is also recommended non-slip footwear, are the support and at least somewhat mitigate the consequences of possible painful sprains.
If one has this to heart everything, an effective muscle building and balance training is no more obstacles.
Not only ankle and foot and calf muscles, but also knee and hip joints are addressed.
I use this device mainly for muscle growth, improved circulation, etc. and less on balance. And I consider myself firmly to a stable furniture, then I can not slip during the foot movements on the Togu that are very intense because of the steepness of the gyroscope in this difficulty. 3
The effect is phenomenal, you can feel how the muscles work and grow thereby. So exactly the desired effect, in order to promote mobility and to minimize risk of falls in daily life.
For balance exercises, but also for heart / circulation I prefer the Bosu Balance Trainer, which to me is the smaller (55 cm) more difficult and therefore more effectively occurs when the large (65 cm).
Oh: AMAZON was super fast as ever. Ordered yesterday - delivered today!
POSTSCRIPT: Now that I have practiced a few days busy, I'm much safer in this great Togu and realize in everyday life a very significant increase in mobility and muscle - and within a few days with daily only about 5-10 minutes use.
