Just saw Yangshengtang, Chinese medicine to lose weight, very healthy. The teacher demonstrated how to do it: put your arms flat on your chest so that they are shoulder-high, tuck in your abdomen and hold your chest up, and lift your legs for an hour every day. It's just not easy to persist. You can choose to do it while watching TV. This method is very effective and useful for bone and blood circulation. You don't have to go on a diet. It's too painful. This is healthier.
