whats a better cardio workout

[Suckmedry]

My running is either

.Stair sprints
.Regular Sprints
. The occasional distance run at varying paces outside.

Running on the treadmill is easier and gets boring mentally, Stationary bike is ok and pretty good for leg strength but I prefer running/sprints

It depends on the type of stationary bike. If it's an Airdyne, I'd take that over a treatmill any day.

the stairmaster can be a great workout. I knos you might think its a little wimmpy but it works. you can go 3 minutes hard 30 seconds or a minute on a easier setting. Juan Diaz does this instead of running. It saves your knees and if you go hard you can really get a great workout.

x2 on the stair master... tried that for the first time the other day. it really kicks your ass more than the bike or treadmill for me.
