Challenge completed!
Active rest day. It was probably the first "summer" day in Finland so I spend most of my day outside with friends and family!

Walking in a nature park:
~55min=100 reps

Basketball:
~5h... A lot of it was just shooting and we also just chilled a lot (definitely didn't play for the whole 5h)!
=100 reps sounds pretty fair for this

Bodyweight workout at the park:
Including; different variants of push-ups, pull-ups, chin-ups, dips, etc.
=150 reps

IN TOTAL

=350 reps
