I was beginning to have back pain this summer after working very long hours sitting and with a lot of stress, and I thought my general weakness and lack of exercise was to blame. I started an 8-week push-up challenge in which I found my max amount of push-ups without stopping (30) and then did 4 times that many (120) in a row, however long it took, gradually reducing the rest time between the sets. I did this 4 days per week. After that process I gained a lot of strength in 8 weeks and ability to do 40 push-ups without stopping. I've now switched to doing my maximum once or twice per day and increasing by 5 every couple weeks. I'm currently at 70, having a hard time going higher, but really feel incredible level of upper body strength from neck to back to abdomen, and am being more careful with my food choices as well. I think I'm now ready to do some more varied exercises, including cardiovascular and other things that challenged me earlier. I find as I'm getting older it's really not worth sacrificing your body for engineering gains, I have too many tech friends who have chronic and sometimes debilitating pain and injuries as a result of the career. What's the point of great accomplishments in technology, career, and wealth if you can't enjoy them because of a broken body? I encourage everyone to find an exercise routine that fits your lifestyle. Push-ups were great for me because I needed no equipment and could fit it easily into my work from home day, and target the areas of my body that were feeling weak.
