Having a strong core takes more than just crunches. Work your core stabilizers with this dumbbell core workout. Mastering this workout will make the 200 crunch challenge a breeze at the end of this program.
We love these adjustable dumbbells from Rep Fitness. They take up very little space and are also very durable compared to other adjustable dumbbells on the market.
Doe deze workout met de beste trainingsapparatuur. We raden aan om een bluetooth borstband hartslagmonitor of een smartwatch te gebruiken voor meer trainingsoptimalisatie & prestatietracking.
