Good to see you writing down your progress. That helped me alot. Once you can devote more time to working out, I'd encourage you to really start increasing the reps on the pushups. Since you can already do 50 in one go. Try doing 10 sets of 20 or doing a full "down" workout. You're already doing somewhat of a down workout by doing 35 pushups, then 30, then 25 ... A proper down workout doesn't skip so if you did a 25 down workout, you'd do 25 pushups, then 24, then 23, all the way down to 0. A 25 down workout would be about 300 pushups. Its an easy way to increase volume and hypertrophy without burning yourself out
