Well, everyone else had a lot of really great input and advice.
I would also add, that it might help you some... to ride more.
From what you are saying... you ride about 4 hours a week... or 16 hours a month. That's a great start, but you won't see your body change drastically with so little time on the bike.
It took me riding 400+ miles a month... or... around 26-30 hours a month on the bike to see improvement.
Still so, even with running up to 80 miles a month, with the riding... I still have cellulite on my legs. On the back and front. It looks better toned and tanned, but it's not gone. Such is life. It's there. If they don't like it, they don't have to look.
Of course, I have gotten compliments on how muscular my legs are these days!
Like I said though, you gotta ride longer than 1-hour sessions to start seeing some improvement. Good luck!
