New Bike and Wrists

[teigyr]

You should build muscle strength as you age.

I'd say to look at bike fit first then go from there. It's important not to put too much weight on your wrists, practice on an indoor bike if it feels awkward.

I am sure you can build core strength. You might not have the "20 something perfect body" thing going on but you can still be pretty darned strong. And lest I offend anyone, I have seen some incredibly fit 50-60 year olds too that put the young'uns to shame.
