Does your father go to work 7 days a week. You can do your spinning on successive days but you need to take some recovery time. Look on Craigslist and let your father help you choose a bike now. You dont need to be spinning all the time, but get out on the roads and have fun mixing with the traffic.
is it normal that my calves have gotten bigger? I've done 2 1-hour rides so far - my dad (huge cyclist) says that it is a the water and blood rushing into the muscle because it is being strained more than usual (never worked my legs besides walking) and he said that in a couple of weeks my legs will start to tone and slim down.. just wanted to see what you guys thought? They got like an inch bigger lol.. and all I see is cyclists with slim and toned legs!!
