I can't hate exercise. I was always an active kid - always riding my bike, climbing trees, jumping on the trampoline, etc. When I was 12 years old, I broke my leg. Couldn't do ANY of the things I loved to do for 18+ weeks! While laying in the hospital with my leg in traction, I swore that I would never take something as simple as walking for granted ever again.
Fast forward 30+ years... Does this mean I always exercise, never miss a walk, ride, swim, weight lifting opportunity? HARDLY! - I also have a LAZY GENE (yes, it's genetic, thankyouverymuch!!

) - I can swim... and I DO! ... but ... I love to lay in the sun by the pool, reading a maggie or my e-reader. And I LOVE to sit on my arse & watch some TV while getting doggie lap time. SO ENJOY walking on the beach, picking up shells, swimming in the ocean, but there's a lot to be said for just laying there, soaking up some good old-fashioned Vitamin D and listening to the sound of the waves...
You don't have to be "either/or" with exercise. And there's a MILLION PLUS things to do. Don't like gyms? Try at-home video work-outs. Like the outdoors? Simple walking around the neighborhood. Don't like outdoors? Try getting a treadmill to put in front of your TV. Don't like biking? Maybe a recumbent bike and a good book is more your style. How about a sport? Tennis? Basketball? Soccer? Softball? Most any sport will do. Like to dance? Boy is that one ever easy! Just turn up the tunes and get jiggy wid'it!!!
THE POINT? Exercise is GOOD for your body. But exercise doesn't have to "hurt" or bore you to tears. Just know this: The older you get, the more you will NOT be able to move COMFORTABLY. Your joints will wear out. Your back will hurt. The knees get creaky, sleep don't come easy, and for women... MENOPAUSE (that's always a barrel of laughs... NOT!) The more you move NOW, the more you find a way to enjoy movement NOW - the better off you'll be when you get older. TRUST ME ON THIS.
