Muscle Rest Timer

Muscle Rest Timer takes the guesswork out of recovery so you can train smarter and build more efficiently.

After every workout, simply log which muscle groups you trained. Muscle Rest Timer automatically starts a personalized countdown for each group — 48 hours for chest, shoulders, and triceps; 72 hours for larger compound groups like back and legs. When a muscle is ready, you'll know.

Need a breather between sets? Tap the built-in 90-second Quick Timer for a full-screen countdown with an audio alert the moment your rest is up — no more staring at the clock.

Features:

• Log your trained muscles in seconds after every session
• Visual countdown timers for each muscle group
• Smart notifications when a muscle group is cleared to train
• 90-second Quick Timer for between-set rest
• Audio tone when your rest timer finishes
• Simple, clean interface built for athletes and casual gym-goers alike

Whether you're lifting five days a week or just getting started, Muscle Rest Timer helps you avoid the #1 mistake in the gym: training before you've recovered. More rest where it counts means more strength, more muscle, and fewer injuries.
