Notch: GTG Watch Timer

Stop forgetting to practice. Start notching reps. Notch is the Watch-first app built for Grease the Groove training, the proven method of doing small sets throughout your day to build strength without burning out. Raise your wrist. Tap. Hang. Tap when done. That's it. WHAT IS GREASE THE GROOVE? Coined by strength coach Pavel Tsatsouline, Grease the Groove (GTG) means doing frequent, sub-maximal sets of one movement throughout the day. Never to failure, always fresh. It's how you go from 3 pull-ups to 15. It's how desk workers build dead hang strength into their commute. It's how you get stronger without a gym membership. The catch is you have to remember to do the sets. That's where Notch comes in.
