All of them were outdoors. To be honest, I have not ridden indoors since 2002. As for power output I have higher power when leaning pack and pulling on the bars. Some riders write about pushing their butt into the seat but when I am putting out max power I don't feel that. I can't say I am changing the angle between my torso and legs by yanking on the bars, but I definitely feel like I put more power out that way instead of trying to get the feeling of pushing my butt into the seat. I do have a left side 4iiii power meter so I might give both ways a try to see exactly what it shows. When climbing after I run out of gas and my legs are screaming, I lean up. I don't think it is because I can put out more power that way. I think it is more "Let's use different muscles or try to get more body weight on the pedals."
