riding a stationary bike or running on a treadmill

Stationary bikes don't work well for me. I prefer running on the treadmill with incline. To each their own though.

running on a treadmill FTW

running outside... but between those two id say the treadmill..

[Fearless]

Treadmill for sure. I hate stationary bikes.

Depends how fast you go and how much resistance you use on the bike or how much incline you use on the treadmill. You can get great workouts with both.

*how about just riding a bike for 20-30 miles?

i run 10 km then sprint at the end.
you can do like 6x 100m sprints and thats ****ing hard and great for power and explosiveness.

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.

Running outside or on a treadmill burns more calories than riding a bike outdoors or on a stationary bike.

For me it's more fun to ride a bike.
