Robin and I have been working out around 6am while the kids are still asleep. But, we were feeling a little under the weather and decided to sleep in yesterday and workout in the evening. The interesting thing is I felt a lot stronger and more flexible in the evening. I decided to look it up and couldn’t find any conclusive information if your body burns more fat or builds more muscle by working out in the morning vs working out in the evening.
Some theories say that there is less food in your body if you workout before eating in the morning, so you’ll burn more fat. Other theories claim that working out when your body doesn’t have enough food trains it to hold onto your fat stores. There is very little information about building muscle except that some theories say that morning cardio workouts can burn muscle since your body wants to maintain a fat store.
For me, I am definitely stronger and more loose in the evenings, but I feel like I have more energy and go to sleep easier when I work out in the morning.
