I think that at the end of the day, regardless of the season, most of us are pretty exhausted from working for 8+ hours. With that said, I definitely think it is a bit worse when fall rolls around and we lose our extra hour of sunlight.

What has helped me the most is pre-packing a gym back the night before and bringing it with me to work. Even when I get tired, remembering that the motivation was there and the bag is packed and ready somewhat helps me get in the mood once I leave the office. I also like drinking a Kombucha right before I leave the office (there's caffeine in it)! 

Hope this helps a bit!

Thanks for the tips! A friend also told me to change into your gym clothes before leaving the office... that way you have no excuse not to hit the gym on the way home. Worth a try!

I just stopped going to the gym recently. I just started my first job out of college and had a big move. I feel like there will never be tim for me to go to the gym. If i started going to the gym again I would be going non stop from 8 am to 9pm.

I understand your guilt for skipping days of workouts. If going after work does not help, maybe you could try working out from the comfort of your home? Depending on the type of workouts you prefer, whether its cardio (you could do 20 min) and weight training (another 15 to 20 min) or a full body workout for 20 min. This would be on your tired days,  I wouldnt tell you to do an hour since you feel tired after work. Good luck!

Try taking a fitness class at the gym that you actually look forward to doing and WANT to go to. If you're excited about it, you're more likely to get in your exercise! Gyms these days have tons of different classes that appeal to such a wide range of different interests.

Thanks for all the great advice guys!
