Just after some feedback on a treadmill routine I do, I'm hopefully fighting in about 12 weeks and I'm just trying to figure out if this is a worthwhile addition to my routine:
1 Min @ 10kph (6.2mph)
1 Min @ 10.5kph (6.5mph)
1 Min @ 11kph (6.8mph)
1 Min @ 12kph (7.5mph)
1 Min @ 13kph (8.1mph)
I do this four times in a row, with a little bit of incline (usually 2.5deg) in the last 5 minutes and the 13kph is normally dragged out to 2.5minutes so the whole thing ends up being about 21 minutes.
Any feedback? Too short? Too slow etc?
