It's a really fun app.

You start off with a test (how many squats can you do in a row all at once without a rest).

From there, the app calculates a strengthening program doing fewer reps but multiple sets of reps with timed breaks between each set.

Every so often you re-test how many you can do all at once.

When you can do 200 in a row all at once without any breaks, the app gives you the option to reset the whole she-bang. That's when I started messing with the handweights to bump it up a bit.

It's easier to do 200 squats in a row than you might think! All that bike riding comes in handy...
