Do wide and diamonds. They will be much harder but you can do less but they will train some the muscles you use for your 100 and will put the focus on those.

Try to set a (new?) goal. Doing 100 a day every day is very possible. I did 40 navy seal burpees (1 burpee is 3 strict pushups basically) for more than a 100 days straight. I still do them every day i don't go to the gym.
