I do a pretty large variety of workout programs and activities, bodyweight exercises, powerlifting, trail running, etc. This has been a good one, easy UI, decent on the social front, program and progression seems pretty functional. Can get a hell of a workout in a short span of time. One complaint is that Im not a fan of how much isolation exercises are utilized (sometimes hundreds and hundreds of sit-ups, for example), but overall am pleased.
