Most fitness apps have you log your workout. RiR helps Fitbod understand how hard your last set actually was. RiR or Reps in Reserve is the number of reps you still had left before failure. So if you finish your last set and feel like you had 2 more reps in the tank, that’s 2 RiR. 🏋️‍♀️ But why? 🤔 👉 Logging RiR gives Fitbod better context for adjusting your future weight, reps, and overall workout intensity with more accuracy. Smarter input = smarter recommendations. 💪 #fitbod #fitbodapp #machinelearningfitness #bestaifitness #rir #repsinreserve #strengthtraining #resistancetraining
