Well sure, pushups aren't the only exercise I do. I do other types of calisthenics as well, but I don't really follow any routine or plan. I just do whatever I feel like and/or have access to. Also, yoga, some hiking/walking, and of course, generally trying to eat more-or-less healthily (high quality fats, lots of protein i.e. eggs, steak, grass-fed butter, MCT oil, Greek yoghurt, avoiding sugar, seed oils and highly processed foods, etc). I also slept on a yoga mat for 3 months, I don't know how much that affected my physique. Now that I'm on the road again I've been sleeping in beds and not been able to keep that great of a routine both in terms of foods and exercise, so we'll see if and how much that's going to affect me.
