I once skipped the first set and wore a pair of red pants. If that set of exercises is really done according to the standard, it will be really tiring. I can sweat a lot, just wear a red hat. Be sure to be in place when doing the action. If you bend, straighten it. Only in this way can it be effective. If it's not that the movements are not in place, it may be that your physical strength is too good.
