Just finishing up your get jacked fast programme with great results . After a week off from dieting i would like to re-run it again , should I
stay with the 30sec on/30sec off intervals or go back to the 15sec/45sec that’s programmed in for the first phase?
could track or Hill sprints replace the elliptical interval portion?
should i go back down in time for treadmill walking or keep the same as week 12?
Thankyou for your help
