There's one big hill on my commute to work that's stopping me from riding. It occurred to me the other day... get off and walk.
Bikes are much faster than walking downhill, faster than walking on flat ground, but when you are old and out of shape, it's okay to declare momentary defeat and walk up hills. It won't even slow you down much.
Obviously you don't want to just jump into something your body can't handle but I think people get caught up on buying "gym equipment" that end up being junk receptacles.
