Training that works around your body, not against it. Bounce Back Smart builds every workout around what is going on with you today: a sore shoulder, a knee that won't fully bend, a back that flares, post-op restrictions, pregnancy, or just the equipment in front of you. Movements that would load a restricted area are never prescribed, and there is always a safe alternative. BUILT AROUND YOU Injury-aware programming. Tell us where it hurts and how it limits you. Your restrictions stay in place until you choose to lift them, so you never have to remember them mid-set. A plan that progresses. Strength, conditioning and mobility that build week over week, with planned lighter weeks, instead of the same three workouts on repeat. A daily check-in. Low energy, poor sleep, sore from last time? Tell us, and today's session adjusts. Your equipment, your time. Home, gym or nothing at all, and sessions that fit the minutes you have. PROGRAMS FOR WHERE YOU ARE Pregnancy and postpartum: training that follows your stage, including a gentler return after a C-section. GLP-1 medications: strength-focused training designed for people using GLP-1 medications. Return to sport: tell us your sport and your target, and training builds toward it. Movement Profile: for wheelchair users, limb differences and limited range of motion. A COACH IN YOUR POCKET Chat with an AI coach. Ask for an easier day, swap a movement you dislike, request legs today, or say your knee flared last night, and your plan updates. A guided workout player with set tracking, an automatic rest timer and a preview of what's next. 700+ demonstration videos so you know exactly what each movement should look like. SEE YOUR PROGRESS Weight, benchmarks, streaks and weekly insights, with shields so one missed day doesn't erase your momentum. Body & Performance (optional): log body fat, lean mass, fat mass and visceral fat from a DEXA scan, and see every value in one place. For your own tracking only. Wearables (optional): connect Apple Health, Oura or WHOOP to see sleep, heart rate and recovery trends next to your training. We only read this data, and it never changes your workouts. TRAIN WITH YOUR TRAINER OR CLINIC Working with a personal trainer or clinic? Connect your account and they can see the progress you choose to share and publish sessions for you. You stay in control and can disconnect at any time. WHO IT'S FOR People coming back from an injury, training around a chronic niggle, returning after a long break, pregnant or postpartum, using a GLP-1 medication, or anyone who wants progressive training that bends around real life. Physician-founded, and built on the belief that "rest until it feels better" isn't a plan. There is almost always something you can train. SUBSCRIPTION (Apple's required auto-renewal text, as before, plus the Terms and Privacy links.) Bounce Back Smart is a general fitness and wellness app. It does not diagnose, treat or provide medical advice. Talk to your doctor or physical therapist before starting any exercise program, and stop if something hurts.
