TalkGym

Talk Gym is a fitness resource offering free strength and running calculators, practical training guides, and printable tools. Its calculators are built around named, published formulas, with sources provided to help users understand how results are estimated. No sign-up is required to use the tools.

For strength training, Talk Gym provides one-rep-max estimates using methods such as NSCA, Epley, and Brzycki, along with RPE-based calculations, plate-loading guidance, percentage and RPE charts, and DOTS and IPF GL scores for comparing lifters across bodyweights. Resources also cover barbell weights and training plans.

For runners, the site offers pace and distance calculations, race-time predictions from 5K through marathon, pace charts, printable race-day pace bands, treadmill conversions, and an NHS-based Couch to 5K tracker and plan. Heart-rate tools include zone calculations and age-based guidance. Talk Gym also publishes fitness articles and free printables, including a New Year plan based on CDC activity guidelines, and sends an optional weekly newsletter with a workout idea and calculator tip. Its calculators provide training estimates, not medical advice.
