Everything in the room.

Four stations, one maximum effort of a few seconds at each, in 10 minutes or less, once a week. Your peak force is recorded in pounds every time. See what happens.

You stand on it for a few minutes before and after the stations. A coach checks a short list of conditions with you first, and you can skip it if any apply.

A water-massage bed. You lie on it fully clothed and stay completely dry, while jets of heated water move beneath a waterproof barrier. Sessions run 6 to 15 minutes.

Check with your doctor first if you have clotting or bleeding conditions, a skin condition, a disc injury, an acute injury or fracture, or an unstable medical condition.

A panel of red and near-infrared light. You stand or sit in front of it with the area you want exposed uncovered. Nothing touches you.

Check with your doctor first if you take photosensitizing medication or have a history of skin cancer or lupus.

The glass-and-copper tower in the lounge. You sit near it, fully clothed, while it runs a program of light, pulsed fields and frequencies.

If you have a pacemaker, insulin pump, or metal chemotherapy port or plating, or you're pregnant or sensitive to flashing light, talk to a coach before your first run.

You lie on a warm mat with copper PEMF coils, in a dark, quiet tent. Stack it with BrainTap in one visit and the pair is $40.

A headset with an LED visor and headphones. You sit with your eyes closed through a guided audio session while light pulses through the visor.
