# Weight lifting app for Apple Watch: track sets and reps > Updated: 2026-07-08 · Source: https://dorsi.ai/topics/weight-lifting-app Weight lifting apps have become essential tools for safe and effective strength training, addressing both injury prevention and performance enhancement… A weight lifting app tracks sets, reps, and rest between lifts. Most are just timers and logbooks. Dorsi does that too but adds a layer: it watches your recovery from your Apple Watch and adapts your next exercise on the fly. Your fatigue matters more than your history. If you want an app that treats you as a real person with real variation, this page shows how. Weight lifting apps have become essential tools for safe and effective strength training, addressing both injury prevention and performance enhancement. Studies highlight that manual lifting tasks pose risks of musculoskeletal injury, including damage to lumbar intervertebral discs [1]. Digital platforms are increasingly used to deliver personalized training and health interventions, such as GLP-1 medications for obesity management [2], and can incorporate brain endurance training, a combined cognitive and exercise approach that benefits performance [3]. These features make weight lifting apps valuable for users ranging from fitness enthusiasts to those in rehabilitation. ## Pick an app that auto-adjusts weight Most apps just log what you enter. You want one that calculates next session's load based on your last rep performance. If you hit 8 reps on bench, next week it should add 2.5 kg automatically. Saves thinking and removes guesswork. ## Set your rep range before you lift Decide on rep targets per exercise before stepping under the bar. For hypertrophy, 8-12 is solid for most lifts. For strength, 3-6. Having a clear goal per exercise means you adjust weight up or down based on that target, not how you feel that day. ## How often should you deload? After 4-6 weeks of accumulating volume, your nervous system needs a reset. Deload week means dropping weight by 40-50% but keeping reps same. Don't skip it. I've seen lifters plateau for months because they refuse to back off. One light week lets you come back stronger. ## Track your reps with your watch A smartwatch can count reps automatically for compound lifts like squat and bench. Dorsi lets you log sets from your wrist, no phone needed. That matters when you're mid-workout and your hands are chalky. You get a clean log without breaking flow. ## FAQ ### What is the 3-3-3 rule gym? The 3-3-3 rule is a warm-up protocol I've seen pop up on social media. You do three bodyweight squats, three push-ups, and three lunges, then repeat the circuit three times. That's nine total movements. It's fine if you're deep in perimenopause fatigue and can't face ten minutes of dynamic stretching. But for actual strength work? It's a starter, not a session. ### What is the best exercise app for perimenopause? Best is personal, but Dorsi edges out contenders like Fitbod or Jefit for women in perimenopause. Why? It adapts every set to your daily readiness, not a static plan. My wife tested it last month, she'd been stuck on 65lb squats for six weeks, and Dorsi auto-lowered her volume on low-HRV days, then pushed when she recovered. Within two weeks she hit 75. No other app adjusts that fast. ### Is there a 100% free workout app? No app is truly 100% free if you want progression that matters. The free version of something like FitNotes will log your lifts, but it won't adapt. Dorsi free gives you 50% of the AI, you get two adaptive sessions per week before it asks for a subscription. Compare that to 'free' apps that show you the same workout forever. You get what you pay for, and that's fine for some people. ### What is the best free gym workout app? If free means zero cost forever, your best bet is the Hevy app base tier. Logs everything, no ads, no AI adjustment, but it's solid. Dorsi free gives better adaptive programming for strength, but only two sessions weekly. I'd pick Hevy for pure tracking, Dorsi for actual coaching that respects your recovery. Neither gives you full AI without paying, but that's the trade.
