Hi all, just a question, lately i have not been able to get back into my normal mode and Ive been resting but slightly using the powerball for at least a week now. Basically my endurance is improving greatly but my speed isn't
For example last week my 90's was 14.5K ish but now it like 15.7K which seems strange...
Anyway i was just wondering if this was normal?
Feedback would be much appreciated
