Ah, spring and summer-- love it-- so great to get outdoors. In fact, my main inspiration for carrying on video workouts in the dead of winter is so that I will maintain fitness for outdoor activities.
I loooove hiking-- our summer vacations are usually based on hiking.
Tennis is so fun. I pretty much suck, but man oh man-- when I start again I so feel it in the butt-- all that getting low. It is just a fun time.
Biking-- I like biking and have gotten some baskets so I can commute to the grocery store this way. I'm not in love with biking like some people though, but my husband and I go for bike rides a few times a week and I love its efficiency for short trips.
I really like swimming laps outdoors, but I wish it was something you could just go and do like running-- it involves more prep, that is for sure.
Running--when you want to get outside and work out without having to do much but put on your shorts and lace up your running shoes.
How can I forget? I love inline skating.
