Smart Progression 2 adjusts exercise recommendations using your logged workout results. As you train, it builds a personal strength–endurance curve for each matching exercise and equipment setup. The curve estimates how your performance changes across rep counts: the strength side reflects your ability at lower reps, while the endurance side reflects how well you sustain performance at higher reps. Your results shape the estimate, so future weight and rep suggestions can become more specific to your training history.
What does it use from my workouts?
It looks at completed sets for the same exercise and equipment. Your reps, load, and logged reps in reserve (RIR) help it interpret how challenging the set was. It also considers how performance changes across sets in a workout, so later-set suggestions can account for fatigue.
What does “strength–endurance curve” mean?
People can perform differently across rep ranges: one person may be relatively stronger for a few reps, while another can sustain more reps at a given load. Smart Progression 2 tracks both aspects in one performance estimate and updates it from your eligible results. It uses that estimate, your programmed target, available equipment, and fatigue during the workout to choose a practical weight and rep suggestion. This describes what the curve represents, not the calculation used to fit it.
Log the reps you actually completed and your actual RIR for the most useful recommendations. Sets without RIR are not used to build the historical estimate. RIR is also needed for Smart Progression 2 to adjust the next set based on a set you just completed.
Does it learn a different formula just for me?
It uses a shared calculation method, with a starting estimate selected for upper- or lower-body exercises. Your logged results shape the personal performance estimate used by that method. So the method is shared, while the estimate and resulting recommendations adapt to your exercise history over time.
What if I have little or no history?
When there is no usable matching history, Smart Progression 2 keeps the prescribed starting weight. After you log a set with actual RIR, it can use that result to start estimating a target for the next set. Recommendations become more grounded as you add eligible workout history.
Can it change both weight and reps?
Yes. It can suggest a different available weight or adjust reps when the exercise allows rep adjustments. Equipment options and any programmed rep range limit what it can recommend. If it cannot find a suitable target, it keeps the prescribed target.
Does a suggestion complete the set for me?
No. A suggestion only fills in a target. Record what you actually did, including your reps and RIR, so later recommendations can use the result.
