Features
One log for lifting and fighting.
Every number explained.
Log a set in seconds, see how recovered each muscle is, and track every lift and every round against your own last session. Each estimate links to the model behind it.
01 · Log
Last time's numbers,
already filled in.
The only question left is whether you beat them. Tick the set and the rest timer starts on its own. Add reps in reserve when you want sharper numbers.

02 · Recover
Train hard without running yourself down.
Work, sleep and training draw on the same reserves. Sparlift keeps the training side honest: a recovery clock for each of 19 muscles and one stress level for your whole week. So you know when to push, and when a lighter week will pay you back.

03 · Progress
You vs. you.
No leaderboards, no strangers' numbers. Every set is measured against your own last time and every lift against where you started, like 55 kg × 7 on the overhead press: one rep more than last week. On the mat it's the same: your rounds, your minutes, your month.
