Cross trainer vs running
Thirty minutes on the cross trainer burns about 185 kcal, a 5 km run about 350. Running wins by 165 kcal.
The difference
165 kcal burned
Running lifts your whole body off the ground with every step, which takes more energy. On the cross trainer your feet never leave the pedals, so it is smoother and easier on your joints.
Time for time running is still higher: 30 minutes of easy running is about 330 kcal against 185. An hour on the cross trainer is about 370. These numbers are for about 70 kg.
If running hurts your knees, the cross trainer keeps you going. In Caltype just type "cross trainer 30 min".
