Workout Progress Calculator
Measure how much you've improved. Enter a starting and current result for any lift, rep count, run time or distance, and see your percentage improvement, weekly rate of progress, and a sensible target for your next session.
Progress is calculated as ((Current - Start) ÷ Start) × 100 for load and reps. For race times, lower duration is better, so the calculation inverts to measure time saved. It generates your next progressive overload target (+2.5% load, +1 rep, or -1% time).

The principle of progressive overload
Progressive overload involves systematically increasing mechanical tension over time. Small incremental jumps (+2.5% load or +1 rep) compound over months into transformative strength adaptations without inducing injury.
Frequently Asked Questions
How fast should I get stronger?
Beginners can add weight almost every session; progress slows to monthly or slower for experienced lifters.
What is progressive overload?
Gradually increasing weight, reps or sets over time so your body keeps adapting.
What if my progress stalls?
Check sleep, protein and recovery, then change reps, volume or exercise variation.
