Im not sure I agree, but its definitely effective.

I tried it out to see how well it would work.

And I hate it.

So, yeah, it works great.

You dont even have to move; you just lay there, holding yourself above the floor.

Stealth provides some convenient videos that show you the proper form for this exercise.

And I did, often, but thats unrelated.

But How Are the Games?

Stealths games have to accomplish two things.

Along with providing good exercise, they also have to be fun enough to want to play.

They mostly succeed, although they are, at their heart, mediocre mobile titles.

I didn’t feel the need for a premium subscription.

Finally, inSpace Escape, you guide a bouncing robot up a series of platforms.

If you were just playing these on their own, they wouldnt hold your attention for long.

But for the scant minutes, youll spend holding a plank, theyre just good enough.

And youll probably be too busy blasting your core or whatever to get bored.

The app also includes leaderboards for each title.

But it is comfortable to use, especially with the pads for your arms.
