Pilates as a workout type on HealthKit, Health Connect, Wear OS and the Google Health API

4 platforms · 2 facts from the sources beyond the names · read 2026-10-18

Pilates has a constant on all four platforms: HKWorkoutActivityType.pilates, ExerciseSessionRecord.EXERCISE_TYPE_PILATES (48), ExerciseType.PILATES (48) and PILATES. The names match once the EXERCISE_TYPE_ prefix, case and separators are removed, and the Health Connect and Wear OS numbers are equal; none of the Apple and Google pages read for this reference maps them to each other. Apple says: “HealthKit provides optimized calorie calculations for this activity based on the data from Apple Watch’s sensors.” A Health Connect session of type EXERCISE_TYPE_PILATES accepts EXERCISE_SEGMENT_TYPE_PILATES segments, besides the 5 segment types every session accepts.

Questions

What is the Health Connect constant for HKWorkoutActivityType.pilates?

ExerciseSessionRecord.EXERCISE_TYPE_PILATES, value 48. The two names match once the EXERCISE_TYPE_ prefix, case and separators are removed; none of the Apple and Google pages read for this reference maps one to the other, so this is a name match, not a documented equivalence.

Is the Wear OS ExerciseType.PILATES id the same number as Health Connect's EXERCISE_TYPE_PILATES?

Yes, both are 48: Health Connect's Jetpack reference prints 48 and the androidx ExerciseType.kt source passes 48. Google does not say the numberings are shared, and 6 other same-name pairs differ.

Which exercise segment types can a Health Connect pilates session contain?

A Health Connect session of type EXERCISE_TYPE_PILATES accepts EXERCISE_SEGMENT_TYPE_PILATES segments, besides the 5 segment types every session accepts. The universal ones are EXERCISE_SEGMENT_TYPE_OTHER_WORKOUT, EXERCISE_SEGMENT_TYPE_PAUSE, EXERCISE_SEGMENT_TYPE_REST, EXERCISE_SEGMENT_TYPE_STRETCHING and EXERCISE_SEGMENT_TYPE_UNKNOWN. ExerciseSegment.isSegmentTypeCompatibleWithSessionType() answers the question in code, and on devices where the record is not handed to the platform API the ExerciseSessionRecord constructor fails with “segmentType and sessionType is not compatible.”

How does HealthKit estimate calories for a pilates workout?

Apple's documentation for HKWorkoutActivityType.pilates says: “HealthKit provides optimized calorie calculations for this activity based on the data from Apple Watch’s sensors.”
