So here is an interesting website with a pushups program:

Maybe after the marathon I should consider doing this? Similar in concept to the beginning running program I did, as well as the “swim a mile” program I did. Basically, start out at a low number of pushups, do workouts three times per week to do more pushups, increasing at a slow number per week. Eventually you can do 100 pushups. Might take longer than 6 weeks, but hey…probably not much longer. Depends on whether you have difficulties and have to repeat any weeks. You’re still getting stronger in any case.
