WHOOP Strain

Monitor your heart rate 24/7 with insight into how strenuous your training and day is to better understand the exertion put on your body.

HOW WE MEASURE STRAIN

Strain is a true measure of how much stress you're putting on your body, both mentally and physically. WHOOP Strain is measured on a proprietary scale of 0 to 21 and can be affected by things like exercise, work, anxiety, running errands, parenting, and more.

LIGHT STRAIN (0-9)

This level of exertion indicates room for active recovery with minimal stress being put on the body.

MODERATE STRAIN (10-13)

This range indicates moderate stress is being put on the body which helps maintain fitness.

HIGH STRAIN (14-17)

This level of exertion indicates increased stress and/ or activity which can help build fitness gains in your training.

OVERREACHING (18-21)

This range indicates all out training or a day full of activities which put significant stress on the body and may be difficult to recover from in the following day.
