Great for Daily Workouts
I’ve been using the SAGE CoreMax for a few weeks now and I can really feel my abs getting stronger. The automatic rebound makes each rep smoother and helps me keep better form. It’s lightweight but feels sturdy, and I can easily fold it up when I’m done. For a compact home machine, it’s surprisingly powerful.
