Most of my cycling is with my 6 year old so I get little actual exercise out of it.
I was thinking of trying something like a runner's weighted vest, but that seems like it would put a lot of weight on my lower back when in a typical road bike posture. (And it seems more expensive than just putting bricks in my saddle bag.)
I imagine the best thing for handling would be to mount as low as possible and not have too much on either side of the bike.
Anybody have any experience adding weight to an upright road bike for training reasons?
Alternatively, any easier way to increase resistance without putting undue stress on knees?
