The struggle to get a good workout when away from a gym (or your home) is real, but toss a few lightweight resistance bands in your go bag, and you can exercise anywhere.
Sure, bodyweight workouts are an awesome option, but add resistance bands to mix, and you have a challenging workout without the gym. Bands come in a variety of colors that each represents a certain thickness, elasticity, and tension, and thus makes it feel like you’re moving some serious weight. There are a few kinds, though I personally like the bands that are closed loops like these ones. They’re simply more versatile than the ones with handles, but both work fine and are compact.
The luggage is always packed tight, but I’m sure I could get what is essentially a rubber band in there.
