When my body’s not being held hostage by the worst of CFS, I prefer to use the T-Tapp approach for fitness. Check the introductory video below.
Note: If you are struggling with CFS, muscle exhaustion is not a goal you want to strive for at this time. There’s “struggling with CFS” and then there’s being on top of it, where you can fatigue or work out your muscles regularly. If you’re in the struggle zone, then you determine what’s best for preserving muscle function without exacerbating the situation. I’m currently working my way back up to the 15 minute routine. Maddeningly slowly.
Doctors with expert advice for CFS/ME sufferers recommend establishing some basic, sustained improvements (good sleep, optimal eating, supplements, tests, stress management, pacing) before embarking on any fitness routine.
