Sticking to exercise is expensive, but some people need to travel frequently because of the nature of their work, so they can't go to the gym on time, and there are also safety problems when they go out to exercise. So every time they go on a business trip, they eat and sleep with peace of mind, and they will sigh, "I don't want to!" ! In fact, each of us has a portable fitness equipment, that is, our own body, and we can do a lot of sports with our own weight, such as leg lifts, frog jumps and lunges. People who travel frequently should not only make good use of this "fitness equipment", but also take one or two books with them, preferably sports. They can not only learn new fitness methods and gain fitness motivation, but also use books as dumbbells, push them up and exercise their arms. It would be better if you could bring a skipping rope. As a fitness equipment, skipping rope is easy to carry and keep daily exercise. If there is not enough space for you to prance, you can put the skipping rope in an S shape with a "cross rope" and then stride around it. You can also use skipping rope to help stretch your limbs. This evening, no matter where you go on business, the stairs are full of exercise equipment. When you go back to the hotel, you can take the stairs step by step, and then lift them step by step, so that you can fully exercise your gluteal muscles. Those chairs and beds will come in handy when you enter the room. You can sit on a stool and lift your legs. You can also practice sit-ups and push-ups in bed.
