I've been waking up at 5am for the past 5 months so I can head to the gym (my first telecom meeting starts at 7am). Because no one is ever going to bother me between 5am and 7am, I've been able to consistently got to the gym at least 3x per week (trying to bump it up to 5x per week for the new year).
I started doing this because it was very difficult for me to consistently go to the gym after work. Things come up, I get tired, friends want to hang out, sometimes I just want to relax after work. But getting up and getting my workout done in the morning has many benefits: Being physical in the morning gives me an energy boost and is a great wake up call, I get my workout out of the way and I don't have to think about it the rest of the day, the gym in generally empty compared to the afternoon, helps me control my sleep cadence, and I feel great knowing that I already accomplished something significant so early in the morning (My whole workout usually spans between 1.5 and 2 hours, I do a lot of stretching and like to take my time). I also try my best not to use my phone aside from music and my workout/fitness apps.
Since I've had such great results from this, I'm thinking of trying to switch it up by working on my side project in the morning and attempting to do the gym in the evening.
