> 2 hours/day at 100% intensity is a lot, but I have found doing something physical everyday to be key to mental health, sleeping better, and general well being. On non-gym days, I go for a 1-2 hours walk in the park/woods in the evening. It's very soothing and meditative (thanks in no small part to being unplugged from electronics), plus you can still get sweaty if you walk fast enough. Obiously, you also get plenty of oxygen vs the gym.
