When is the best time to go to the gym? Is it better to go first thing in the morning? Do you burn more fat if you train in the morning? Does it even matter? Well let's put it into perspective.
If you are someone who struggles to get up in the morning and I set you a workout programme you had to do 4 mornings per week how consistent would you be? My guess is not very. Sometimes getting hung up on such small details isn't worth it. Unless you are a professional athlete I think you should set your training to work around you.
If it suits your schedule to train in the evenings then train in the evenings. If it's in the morning before work then do that. Finding what works for you as an individual is key. It will increase the chances of you being consistent which in the long run is going to be more important than worrying about the smaller details. To my knowledge there isn't any evidence strongly supporting greater fat loss or improved body composition by training in the morning.
Don’t be that person who doesn't end up going to the gym at all because you got hung up on smaller details that are not more important than consistently turning up.
