TRIMP Calculator
Calculate training impulse using Banister, Edwards or Lucia TRIMP and review weekly load, monotony and strain.
Use a tested HRmax or a stable sport-specific estimate when possible.
Method comparison for your data
Part of the comparison uses an estimated zone distribution from duration and HRR. Track one method consistently for trends.
Weekly TRIMP
Balanced week profile
High monotony and strain do not prove overtraining, but they help flag a monotonous or sharply heavy week.
Calculate training impulse
TRIMP search intent is about turning duration and intensity into a training-load score. This calculator supports Banister HRR, Edwards zone minutes and Lucia three-zone scoring.
Banister TRIMP uses duration, heart-rate reserve and sex-specific constants.
