There will be a bottleneck in spinning to lose weight. Generally speaking, the first month has no obvious effect, and the second month begins to enter the obvious weight loss stage. I lost about 5 kg, and it didn't change for a week or so, and then it began to decline, and it began to change for a week or so after about 5 kg. Until you lose 20 kilograms, the bottleneck period will be longer, and it may not change for more than half a month, but then you are used to exercise. As long as you continue, your figure curve will come out, and it will continue to decline after the bottleneck period.
If you want to lose weight faster, you can do yoga, pedal or group exercises after a cycling class. If you are a man, you can run for half an hour.
Spinning is already the highest intensity aerobic exercise, which means it is the most useful exercise to lose weight, and it can also improve heart and lung function, which is good for the body. As for the leg lines, you can look at these riding instructors. Whose legs are ugly?
