What's different about Leenen for this niche
Watch-first delivery
Strength platforms try to bolt cardio on. We treat the watch as a first-class output target: send a planned session to Garmin Connect™ and your client hits start on their watch, no app needed mid-session.
One wearables integration (coming soon)
Garmin, Strava, Polar, Whoop, Oura, Fitbit, Withings — planned through one normalised API, so we're not maintaining six separate OAuth flows. Apple Health and Health Connect come first, in the mobile app.
Training load that flags injury risk
Acute:Chronic Workload Ratio rolls up automatically and lights amber/red when it spikes. You don't have to do the maths in your head every Sunday review.
