Notes
(10 mins run + a couple minutes of rest) * 4 sets (rest needed due to multitasking other things at home)
set 1: No incline, around 6.8mph (8:49/mi) after some warmup
set 2: 1-2% incline, around 6.8mph (8:49/mi)
set 3: started at 1% and added 0.5% every minute until 5%, 7mph (8:34/mi)
set 4: started at 1% and added 1% every minute until 9%, 6.8mph (8:49/mi)
Last set after 6% incline is difficult
