The app's algorithms for determining your weight, reps, and sets are a bit complex, but act in fairly predictable ways in most cases.
- weight is increased by a few percentage points each week, and
- if the next weight increment is outside of that range (like going from the 10lb to the 15lb dumbbells), it adds a rep to each set instead.
- Set numbers are adjusted by how pumped, sore, and beat up from volume you feel.
- Low pumps, barely sore, and rating workouts as easy = more sets
- Good pumps, soreness just healing on time, and your workload as pushing your limits, = no change in sets
- Amazing pumps, so sore that you can't heal on time, and too much volume = fewer sets
These calculations are continuous and future sessions are influenced by your feedback, which means the app is always fine-tuning the weight, reps, and volume to your exact needs. If you ever disagree with its prescription, by all means manually add or delete sets or overwrite the weight; you can make any changes at any time.
