It's a modified take on the Ab-Ripper X. Increase repetitions once you feel comfortable with the routine. The duration of the routine depends on your level of fitness (not everyone will finish under 18 minutes) , go at your own speed but don't hold back, be consistent with the flow. You can do this routine twice a week or as much as you'd like once you get the flow of it.
Doe deze workout met de beste trainingsapparatuur. We raden aan om een bluetooth borstband hartslagmonitor of een smartwatch te gebruiken voor meer trainingsoptimalisatie & prestatietracking.
