We have a travel trailer and usually do a lot of hiking on trips. I really like trekking poles. Using the poles, I get a great upper body workout while taking some weight and impact of my legs and hips.
On less active trips, I'll bring a 5lb ankle weight and do Margaret Richard's
Getting Better.
I have dozens of workouts loaded on to my iPad. Streaming isn't that great in campgrounds.
A long time ago, I took a resistance ball on a trailer trip. When we got to high elevations, the ball expanded about 1.5 times it's normal size. I was worried it was going to 'splode! I didn't bring any balls after that.
Do you bring any fitness equipment or videos on vacations?
