WITH runs in your browser, but you can install it and it'll open full-screen like a native app — no browser bar, no address bar.
Open Settings inside the app (tap the gear, top-right) and tap Install App. Confirm the prompt.
Tap the Share button (the box with the arrow) → "Add to Home Screen" on iPhone, or look for the install icon in Safari's address bar / Share → "Add to Dock" on Mac.
No install support on Firefox, on any device — that's a Firefox limitation, not a WITH one. Just keep the tab open, everything still works.
Once installed, open it like any other app on your device.

Wave: build up, hold at the top, ease off slowly.
Steady: one even effort for the whole 15 seconds.
Steady plus bursts: hold at half, add short harder bursts.
Mind to muscle focused reps work too. Even light weights are enough if you put in the work.
If something hurts, stop.
Never act on a cue while driving, near water, or when sick.
