HIIT question

[BEN]

during an hiit session should i be running as fast as I can or just above normal running speed? also how long is the average HIIT session for you guys

[GhettoSmurf]

average HIIT session is prolly about 10-120 minutes

during a HIIT session you warm up, then run YOUR FASTEST for like 15 seconds or so, then jog or even walk for 30 seconds or so, and then run your FASTEST again for another 15 seconds, etc.
