The treadmill used to be my worst enemy. Why anyone would want to spend more than 5 minutes on the thing blew my mind.
But now, I’m coming to see it as very useful in this 100+ degree summer weather we’ve been having. Running with humidity and 100 degrees? Ehh, no thanks.
I think I’ve talked about sprinting on the TM before, but I don’t know.
I used to do this [lame] TM routine where I’d increase the speed 0.5 mph per minute but would have the incline all the way up and be holding on… I I
Sure I’d sweat and it would read that I burned a lot of calories and ultimately it was semi-helpful, but I spent at least an hour doing that and probably wasn’t getting the best results.
In the past year I’ve been doing 20-30 minutes of sprints. I started out 1 min walking @ 4 mph, 30 seconds sprinting @ around 8 mph. Or… something similar.
Then, about a month ago I switched it up to where I walked 30 seconds @ 4 mph and ran 15 secs @ 8.5-9.0 mph.
Today, I switched it up and walked 30 seconds @ 4 mph and 20 sec @ 10 mph for 25 minutes.
Start slower and walk longer, but make sure to increase these intervals quickly, before your body gets used to what you are doing.
My goal is to switch up my interval time and/or speed every 2 weeks.
Below I’ve posted some links to what others do for TM intervals:
