I tested Crazy Fitness Gadgets vs Ryan Trahan

Used as a reaction-speed challenge that left both of them exhausted, with no formal verdict.

A rope that counts skips so you can't cheat, used for a 30-second skipping challenge.

Used as a massage break; Ryan loved it, while Arun gave no formal verdict.

Wrist-strength gadget scored by how fast you can spin it, used in a head-to-head challenge.

The simplest gadget on the list, with dice that choose the exercise, but still chaotic.

Used for a virtual boxing match and he found seeing his hands in VR impressive.

A weighted hula hoop that counts swings, which Arun said terrifies him.

An app-controlled electric ab belt used for a pain-tolerance showdown; he found it very weird.
