I've been fighting hand pain ever since I got back on my bike in 2013. The problem (aside from arthritis in my left thumb) is that I rest too much weight on the 'bars.

I can keep weight off my hands when coasting and when pedaling all out. I just can't figure out how to engage the muscles that hold me up while coasting, etc., when I pedal normally.

Am I missing something technique-wise? If so, what is it?

Thanks in advance. BTW, I'm way overweight, and I'm 72.
