Free strength training tools
Three calculators, free in your browser. No login, no clutter. Everything they compute, the Mekimeki app tracks automatically while you train.
1RM Calculator
Estimate your one-rep max from any hard set, with Brzycki, Epley, or hybrid formulas and a training percentage table.
Try it free ›Plate Calculator
Stack one side of the bar and see instantly whether it matches your target, and by how much per side.
Try it free ›Volume Calculator
Total your session volume, sets × reps × weight, per exercise and overall.
Try it free ›Why are these free?
Because they're a preview. Each tool answers one question once; Mekimeki answers it on every set: estimated 1RM and PRs calculated as you log, a plate calculator built into the session view, and volume totalled per exercise and per session.
Let the app do the math
Everything these calculators do, Mekimeki tracks automatically while you train.
