GTG Pro

GTG Pro runs grease the groove training for you: many easy sets spread through the day, never to failure.

Pick push-ups, pull-ups or your own exercise. Test your max once, and the app builds the plan: half your max per set, 10 sets a day, spread across the hours you choose. Each reminder tells you the reps. Touch and hold it, tap Log, and the set is saved without opening the app.

Every 14 days it asks you to retest. Your new max sets the next two weeks, so the reps grow as you do.

HOW IT WORKS • Test your max: one set of as many clean reps as you can. • Get a plan: reps per set, sets per day, a reminder window and rest days. • Do a set when the reminder comes, and log it from the notification. • Retest every 14 days. Keep your current reps instead if you need to.

WHAT YOU SEE • Today: each program's reps, the sets left today and the next reminder. • Streaks, adherence and perfect days. Rest days never break a streak. • A chart of your max over time, and your reps for each of the last 14 days. • Every program's streak in one place.

YOUR PLAN, YOUR DAY • Set the intensity from 30% to 80% of your max. • Choose 1 to 20 sets a day and the hours reminders may come. • Pick rest days. Pause a program and pick it up later. • Run several programs at once, each with its own reminders, kept 10 minutes apart.

IPHONE AND IPAD • Programs and sets sync through your own iCloud. There is nothing to sign in to. • Log a set on one device and it counts on the other. • Choose which device reminds you, so they never both buzz for the same set.

PRIVATE BY DESIGN No account, no ads, no tracking. Your training is kept on your devices and in your own iCloud, where only you can read it.

TRAIN SAFELY Every set should feel easy. Stop when your form breaks, and rest if anything hurts. GTG Pro counts reps. It is not medical advice.
