After working out for a while doing only burpees and pullups my brother and I started this program. We started at level 4.
D1L4: Forgot to track
D2L4: 10 min.
D3L4: 7 min.
(5x4 pullups, 2x20 pushups, 1x41 squats)
It's very, very hot and humid here right now so that's about all we could pull off. Pretty decent start nonetheless, I think?
