Professionele core-training bal

The little bumps provide just enough grip to keep it steady during my mat work. I can actually feel my deep abs engaging way more than with just floor exercises alone. It’s a simple upgrade that makes a real difference in my Pilates sessions.

Didn't expect a little ball to make such a difference, but squeezing it between my knees during ab work keeps me from cheating with my lower back. It's firm enough to actually hold its shape, not squishy like the cheap one I had before. My core feels worked in a way mat exercises alone never managed

I've been using this in my mat Pilates routine and it's made a real difference for keeping my hips aligned during leg circles. The ball has just enough give that it doesn't dig into my lower back but still forces my core to work. Way better than the flimsy one I had before.
