It's more than possible for you to get up to 100 push-ups, they are just for men after all. Push-ups are one of the best total body exercises ever, and it amazes me how many women can't even do 1 push-up with good form.
Push-ups are so great because they can be done no matter where you are and they can help workout not just your chest, but shoulders, abs and the rest of your torso too.
If you need help with form before starting to work up to the coveted 100 push-ups, just watch the video below to get a crash course.
How many push-ups can you do today? Without stopping! This is the starting place where you will progress from. Getting up to 100 push-ups is a workout program in itself. It takes commitment to a training program and motivation.
You're going to have to work on push-ups in each workout... that means if you're following one of my workouts then you're working out three days a week (strength training).
Spend just 5 of your sets doing push-ups. I recommend doing pyramid sets... with each week increasing in intensity and set number and rest period.
The first week rest 60-80 seconds between your push-up sets. Aim for the first set to be 1/2 of your max number, the next set going up by 3 push-ups. Then the third and fourth set be the same as the first. Your final set... all the way to max.
The next week, decrease rest to 60 seconds max. Increase all the sets by 3 push-ups, still with the final set going to 100.
Continue with this pattern for a total of 4-5 weeks of training. Increasing reps and decreasing time. The final workout rest up and aim for your new maximum! Let me know your number.
