Cross-trainer & Press-ups
Combining sets of 30-second reps on the cross-trainer – sprint-steady-sprint-steady – with press-ups on the floor can leave you feeling nauseous. But work through it!
* Set cross-trainer at moderate resistance so you can keep up speed
* Vary sprints. Use arm rods for some and not for others
* Only take 30 seconds’ rest when you do your press-ups. Swap quickly
