About Sparlift
A free training log for people who lift and fight, made by one person who does both.
Sparlift is a training log for people who lift and also train a combat sport: BJJ, Muay Thai, boxing or MMA. Log a set in 3 taps and a class in 2, even with no signal, and see which muscles are still loaded before you train again.
Who makes it
Sparlift is made by one person. I've played sport since I was a kid and have trained for years, these days boxing/MMA and lifting. I'm not a coach or a pro fighter. I like training and I like data, and I couldn't find a log that understood both halves of the week. Sparlift started as that log.
How it works
- Logging comes first. If logging takes more than a few taps, people stop. Everything else is built on a complete log.
- Numbers you can check. Every calculation, from estimated one-rep max to recovery, is written up in the docs with its formula and how strong the evidence is. When a number is a guess, the docs say so.
- Estimates, not diagnoses. Recovery tracking is for orientation, not medical advice.
- Your data is yours. No ads, no tracking cookies, and your data is never sold. You can erase it from Settings at any time. See the privacy policy.
- Free. Sparlift costs nothing to use.
How the posts are written
Posts come from first-hand training and from numbers in real training logs. When a claim comes from research, the post links to it. AI tools help with editing and translation; a person checks every word and every number before anything is published.
