I guess to help those out better at this than me, I'll ask some questions first I know will be coming:
1. What are your injuries from riding a bike that you say weight training assists? Knowing this may bias people's answers in a certain direction to help more.
2. Do you currently track your bike riding in some kind of way that quantifies duration and intensity?
3. Do you have any special dietary choices or restrictions from the norm? Related to perhaps carb, protein, diabetes, medicines, etc..?
