Your last set should tell you what to do next. Gymbro is a lifting log and workout tracker for lifters who want structured progress without spreadsheets or gym math. Log weight, reps and effort, see what you did last time, then get a clear target for your next set and upcoming workouts. No account is required to begin. Workout logging works offline, so your session keeps moving even when the gym has no signal. Sign in only if you want secure cloud backup and cross-device sync. Progressive overload that responds to you Choose a target rep range, an RPE or RIR target, and the weight increments available for each exercise. Gymbro analyses every completed set and adjusts the next weight and rep target around your actual performance. • Reach the top of your rep range and Gymbro moves the target forward • Miss the minimum or report high fatigue and it can reduce the load • Stay inside the target range and it keeps the progression controlled • Recommendations match the plates, dumbbells or machine increments you use This is progressive overload you can act on during the workout, not another graph to interpret later. Works with Apple Health Connect Gymbro to Apple Health and keep your training and body data in one place: • Completed workouts are saved to Apple Health as strength training sessions, with an estimated calorie count, so they count toward your daily activity • Body weight and body fat you log in Gymbro appear in Apple Health • Steps, active calories, body weight and body fat come back into Gymbro, so your measurements stay current without double entry Apple Health sync is optional and off until you connect. You choose which data to share and can disconnect at any time in Settings. Health data is never used for advertising and never sold. Plan your training week Use the weekly workout planner to assign routines to each training day and keep your program visible in one schedule. See workout and rest days at a glance, start the planned session, or edit, swap and remove scheduled routines as your week changes. Log without breaking focus • Build unlimited custom routines or start with ready-made programs • Record weight, reps, RPE or RIR in seconds • See previous values while you train • Add warm-up, normal, failure and drop sets • Create supersets and automatically calculate warm-up sets • Use per-exercise rest timers, a stopwatch, and pause or resume • Save exercise notes for form cues and machine settings • Train in kilograms or pounds See more than workout history Gymbro turns completed sessions into useful feedback: • Personal records for weight, reps, volume, duration and distance • Estimated one-rep max (1RM) and exercise performance charts • Weekly reports for volume, intensity, consistency and progress • Comparisons with your previous week • Workout calendar, history and weekly streaks • Muscle heatmaps showing where your training volume went Train from Apple Watch Start a workout on iPhone and continue from your wrist. Update sets, weight, reps and effort, check your heart rate, and follow the rest timer without keeping your phone in your hand. Built around your training • 300+ exercises with instructions • Custom exercises and routines • 1RM calculator, plate calculator, TDEE and BMI calculators • Separate profiles for a partner, friend or client • Hydration, supplement, body-weight and calorie tracking Whether you train for strength, bodybuilding, powerlifting or general fitness, Gymbro keeps the process simple: record the work, understand the result, and know what to do next.
