There are fewer sports restrictions suitable for the whole family. Old people and children are not suitable for high strength and difficulty, and treadmills and barbells are not recommended. You can buy an exercise bike, elastic rope and yoga mat, which is safer and simpler, and the strength is not very great. Yoga movements must be in place. If the range of exercise is too small, the muscles involved in the exercise can't fully stretch or contract, which makes the training get twice the result with half the effort. (Old people must choose simple and slow movements) Recommendation: Yoga basic exercise bike is more suitable for all ages than yoga and elastic rope. Moreover, when riding an exercise bike, about 90% of the extensor muscles of the human body participate in exercise, which is very beneficial to extensor muscles that rarely participate in exercise. Recommended: Ankang, Li Jian, Xing Chi, KM 1930, etc. , international and domestic famous brands! Personally, I use the KM 1930 exercise bike, and I can experience riding without leaving home, which is not available in other exercise bikes.
