I’m type-1, but I hope you don’t mind me chiming in on a type-2 discussion - I think it applies to us all!
For so many years I really had a difficult time finding an exercise program that I liked enough to stick with, and I was not in great shape and heavier than I should have been. But, I bought a bike last March and started cycling, and I was amazed at how much fun I had, and how quickly I got into shape. It’s very low-impact, and doesn’t even seem like exercise! It made me feel like a kid again, actually.
I started commuting to work and running errands on my bike, and not only is that a great way to ensure you fit exercise into your daily routine, but it also saves a ton of money on gas/car maintenance. I have surprised myself by keeping with it, I have lost about 15 lbs, and I have never been happier or in better shape. This is the first “exercise” program I’ve been able to stick with for more than 6 weeks - and I would DEFINITELY recommend it. Just make sure you get padded shorts!
