My personal exercise equipment recommendation: AB slide!

This is a four-wheel ab slide purchased for abdominal exercises.

I am only investing 10 minutes a day.

I am doing a total of three sets, each consisting of three repetitions of five rounds back and forth.

At first, it was so difficult that even doing one was hard, and I would tremble and be afraid my jaw would break every time I did it, but these days I am so accustomed that I can do three sets in a row without problems.

It's a bit difficult to get back to where I started.

I really feel like my abs are getting stronger, and I think it's because of my core muscles. It feels like my posture is improving and I can tell the difference.
