I have heard all sides of the debate when regarding what time is best to go to the gym, half of my friends say go in the morning it wakes you up and the other half shout back go at night its better to rest your muscles after you work out. I personally agree with the half that say work out in the morning to wake yourself up and get that nice boost of energy that is needed to get me through the day. However with the recent studies that have been done on mice regarding oxygen levels and circadian rhythm, see my last post for this to make sense, scientist now think that there is a way to use the time of the day to boost how much you work out and how much effort you will put into working out. All cells in our body including the muscles, are adapting to the changing conditions 24 hours a day 7 days a week. If this is true than scientist at Northwestern Medicine theorized that there could possibly be a way to manipulate the oxygen to truly boost our work outs even more so than, creatine, pre-work out, etc.

Lets look at what we know right now, first off there is the fact that all experiments up to this point have been done on mice so what we say works for them might not work for us humans. However that being said they found that while they made the mice exercise at different times of the day including night time, they found that because mice by nature are nocturnal creatures worked out well in the night time but not as well in the day time. This ties back into the circadian clock, while the mice clocks have been tuned into the night this means that their muscles are processing the nutrients like salt and sugar better at night when compared to the day which is when they sleep. The scientist then took this and conlcuded that if you applied this to humans in the same enivorment we would see a similar result except for the day.

In conclusion, to answer the question as of right now the best time to work out is anytime during the day but make sure it is between 7 A.M. and 5 P.M. as that is when most humans have geared themselves to be the most active and most awake. This post was mainly for debate purposes with a little side of science backing my belief but let me know what y’all believe and think.
