Why Track Your Inspiratory Muscle Training?
For athletes chasing marginal gains, tracking the numbers matters as much as doing the training. On-device figures tell you what happened in one session, but a proper trend line across weeks is what shows whether your program is actually working.
- See load, power and volume trends session to session
- Catch a plateau early and adjust your program
- Compare progress across a squad or training group
- Just a few minutes, twice a day
POWERbreathe K3 vs K4 vs K5
All K-Series devices share the same patented tapered-loading system. The K4 adds Breathe-Link software connectivity on top of the K3's on-device readout, without the K5's full live biofeedback and waveform display.
| Model | Best for | Key difference |
|---|---|---|
| K3 | Individual users | On-device results only, no software needed |
| K4 | Data-focused users | Simplified Breathe-Link connection |
| K5 | Elite athletes, teams, clinics | Full live biofeedback, waveforms, 30 user profiles |
Who the K4 Is For
- Athletes and coaches who want live, on-screen feedback during training
- Individuals tracking respiratory strength gains over months, not just single sessions
- Small squads or training groups needing several user profiles on one device
- Anyone stepping up from the K3 who wants software-based analysis
Breathe-Link Software and Live Feedback
The K4's Breathe-Link software connects to a desktop or laptop by USB and turns each session into a readable trend, not just a number on a small screen.
- Real-time display of Load, Power, Volume, Flow and Energy during each session
- Historical trend charts across up to 1,200 stored sessions per user
- Up to 10 user profiles, suited to a small squad, clinic or family

The K4 is a training device, not a therapeutic treatment. If you have a diagnosed respiratory or cardiovascular condition, talk to your doctor or physiotherapist before starting IMT.
