I can never get 60 mins at a stretch to exercise, so can I exercise twice for 30 mins each time?
A. It is better to exercise twice a day for 30 mins rather than doing a long session of 60 mins. This is because each time you exercise for 30 mins the metabolism stays high for the next couple of hours. So twice a day your metabolism would stay high instead of once if you had a single long session. This means that after exercise you burn stored fat twice during the day for a couple of hours instead of once.
