RIRLift: Hypertrophy Log

Meet Riv, your AI lifting coach. Adjust your plan, understand your progress, and turn logged sets into your next step. Train on iPhone or Apple Watch.

Get stronger with a plan, an AI coach, and a workout log that helps you decide what to do next.

RIRLift brings strength training together on iPhone and Apple Watch. Build your program, track your sets, and get guidance grounded in the training you actually do.

MEET RIV, YOUR AI LIFTING COACH Ask about your progress, plan your next workout, or adjust a session when your schedule changes. Riv works with your training history to put its advice in context. Preview proposed workout and program changes before applying them.

KNOW WHAT TO LIFT NEXT Log your weight, reps, and reps in reserve — how many more reps you could have completed. RIRLift uses your logged performance and effort to guide your next working weight, with explanations you can inspect.

BUILD A PLAN THAT FITS YOUR LIFE Start with a program based on your goals, experience, schedule, and equipment, or build your own routines. Follow a multiweek Journey to keep your sessions organized and see how your lifts develop across your program.

TRAIN ON IPHONE OR APPLE WATCH Follow planned workouts and log sets from your wrist, even with your iPhone left behind. Keep your exercises, rep targets, rest timers, and effort targets close at hand throughout the session.

SEE YOUR PROGRESS Track personal records, strength trends, and weekly hard sets by muscle. Use the muscle map to understand where your training volume is going, alongside recovery estimates based on your logged work.

KEEP YOUR WORKOUT MOVING • Exercise demonstrations and instructions • Warm-up sets, supersets, drop sets, and rest-pause work • Exercise swaps when equipment is unavailable • A plate calculator to help load the bar • Workout notes, history, and custom exercises • Optional workout saving to Apple Health

BRING YOUR TRAINING HISTORY Import workout exports from Hevy, Strong, or FitNotes so you can keep building on the work you have already done.
