Get in Plank-position and do: 1 mountain climber, 1 knee-to-elbow plank, 1 grasshopper, 1 mini scorpion and 1 leg lift (all 5 left and right): this counts as one rep (you could add ankle weights). Start each following 20s with the next exercise, e.g.: first 20 secs start with mountain climber, rest, start the second 20 secs with elbow to knee, rest, 3rd with grasshopper and so on (...so each exercise is at the beginning twice). Begin the first 5 with the same foot and start the last (...) five with the other. Try to hold form when it gets tougher, the reverse planks are to somewhat shift the focus.
Doe deze workout met de beste trainingsapparatuur. We raden aan om een bluetooth borstband hartslagmonitor of een smartwatch te gebruiken voor meer trainingsoptimalisatie & prestatietracking.
