Trying to get my exercise regime in order as well as my eating... Did a "sprints" session in the gym yesterday and went for 1 minute sprints with 1 or 2 minutes of walking to recover in between.
I have seen some comments about much shorter sprints being better. So am I sprinting too long and slow?
I am particularly interested in the science of what's happening to my body during and after the sprint...
...for info, I set the treadmill at 14 to 15 kmh (10 to 11 mph??) for my "sprints" - as I can do 10 sets of 1 minute at this pace, and it doesn't feel too unsafe on the treadmill at that speed (but on the edge for the 250 lb me - don't walk behind my treadmill just in case I fly off...I will probably squash you flat).
Outside I am happier to sprint full speed for shorter distance, but my lifestyle does drive me to need to do some sprint sessions in the gym (eg time, weather here in the UK, location of work etc).
