Good map to 20 pull-ups

I was able to do 20 Marine-quality pull-ups (no kips or swings) in my late teens and now, at 46, am looking to get back to that ability. Purchased this app and like the roadmap it gives you each day to get to your goal.

Wish the app had more suggestions for when you can't do the daily routine fully (e.g. do negatives for the pull-ups you can't complete) and it probably also needs a separate build-up track for those who can't do one pull up yet so they can get to the first pull up routine.

Decent idea for an app though and I have purchased the push ups and squats one too.

By the way, this pull up routine works just as well for dips as it does for pull-ups.

Almost there. Could be improved.

There should be a test to start to determine where you are with pull-ups. That’s where you start your program. I had to tap through the program until I got to a point where I thought I should start. The text as to how many to do and the rest time is pretty small. I can’t see what I’m doing on the app.

Friendly app for all level users

App is easy to use and you don't have to start from a strong point. This app gets you from the very beginning to 20 at your pace with daily detailed guidance.
