I've been thinking of a recumbent for ages, mainly because I like the look of them and the adult go kart effect. However I only have a Marin Hawkhill that isn't used much and my fitness levels are a little low though I am working on it. I have a mill for indoor cycling and also some gym equipment. Short of getting a recumbent cycle trainer is there any methods for working the muscles I would predominantly use with a recumbent? I have been toying with the idea of using a recumbent for work, lugging tools and stuff, instead of the car for the local jobs but didn't want to invest and find that I am knackered and useless a mile down the road. Thank you.
