In fact it is one of the best crunches you can make, realized the 21 days plan which make sense, because you might not try to make crunches all days, I'm not a fun to make workout (prefer squash sport) but if you want to optimize the core this is the device for this.
That was a nice surprise. First time I used this my abs were actually sore for a day. Really nice core work out. Even gets some of your shoulders in on the action.
Really cut bathing suit and fits perfect! Butt is totally covered up and top is not so tiny that you worry!.
They fit me great. They are easy to get on and off, and they are easy to walk around in and stand on my feet all day.
I’m not even THAT big chested, at 36C, it says a lot about the sports bra designs designated high impact, because none would support well enough for no pain. This took that annoyance away! And fit perfectly to size. I have had hell finding decently high impact bras. Most in stores say they are, but the jumping jacks prove them wrong quickly.
