Rust Strength

Rust Strength answers the question every lifter has mid-workout: how much should I put on the bar for the next set? Log a set with the weight, the reps, and how hard it felt on the RPE scale. Rust Strength works out an estimated one-rep max from that, then suggests a weight for your next set aimed at reaching failure inside the rep range you chose. Every suggestion is rounded to a weight the machine in front of you can actually be set to, because a recommendation of 147 lb is useless on a stack that moves in tens. BUILT FOR TRAINING IN DIFFERENT GYMS Machines are not consistent. A chest press at one gym does not feel like a chest press at another, and plate-loaded, selectorised and cable setups all label weight differently. Rust Strength records which machine each set was performed on and rounds to that machine's own increment, so a session in a hotel gym does not corrupt what it knows…
