Hey nice work. I have been getting into weight lifting once I hit 40 and really enjoy it. I suggest looking at stronglifts app if you want to see how to grow this. That app is great and after a week I had gone to the premium subscription.

I feel you are missing customers with the site saying that the app assumes you know how to do 5/3/1.

You should have a how to page on your site. Anyway great work congrats.
