How do I add a workout to Garmin Connect without a watch?

Configure the sport, duration and intensity in FIT Generator, download the generated .fit file and import it into Garmin Connect via Import Data. The file contains per-second heart rate records, calories, Training Effect, TSS and time in zones.

How is maximum heart rate estimated?

Without a measured value, HRmax is estimated from age using the Tanaka formula (208 minus 0.7 times age). For women the Gulati formula (206 minus 0.88 times age) is used, which was validated on over 5000 women. A self-measured value always takes precedence.

Does the generated FIT file work with Amazfit Zepp?

Yes. Zepp reads the per-second heart rate records, so PAI accumulates correctly and Training Effect is displayed. Zepp's own training load score is only calculated for native device recordings, which is a platform limitation.

Is my data uploaded anywhere?

No. The heart rate simulation, all metric calculations and the FIT file encoding run entirely in your browser. Nothing is sent to a server and no account is required.

Logging judo training without a heart rate monitor

Typical effort: 85–93 % of maximum heart rate (Franchini 2013; Slimani 2018). Generate a complete .fit file for a session you could not record.

Why the band comes off

Kumi-kata means both athletes grip the gi constantly, and a wrist band is directly in the way. It scratches, it catches on sleeves, and competition rules prohibit hard objects on the body.

What heart rate to expect

Randori and shiai reach 85–93 % of maximum heart rate. Judo shares the wrestling pattern: gripping is isometric, so heart rate rises faster than aerobic demand, while throws and ground transitions add short maximal bursts on top.

Typical session structure

A 90-minute session usually runs 10 min ukemi and warm-up, 15 min nage-waza technique, 10 min uchi-komi and 4 randori rounds of about 4 minutes.
