Angelina it takes much more training time to see how best to move in the belt to avoid pain or injury
Angelina, you can walk with the belt, go shopping... We all make these things, but running specially at those awesome rhythms is not recommended thing.
The impact on soil is much more brutal, and your body just have 1 way to absorb it, it's natural way.
When you run long distance as she says, at the end the muscles, that in first kilometers help to absorb part of impact, are exhausted and impact go directly to legs bounds and bones.
If you add to this the fact of that with belt we tend to walk with legs a little bit more open, it is a diabolical cocktail.
Can you play a friendly match of tennis with belt? Yes, rhythm is no so high and movements are short and fast, but... Long distances? No. And of running and training I am a bit aware! 😄
