Honey, no instrument can achieve the effect of reducing fat alone. If you want to lose weight through a strength bike, then you need to make it aerobic training. The so-called aerobic training needs to focus on two aspects: 1. Time usually consumes muscle glycogen in the first 20 minutes of exercise, and then slowly fat begins to supply the energy consumed by exercise. The ideal exercise time is 40~50 minutes. 2. Heart rate Heart rate needs to reach the target heart rate. Of course, it's best to install a heart rate monitor for your electric bike. If not, you need to buy one more. Here is a method to calculate the target heart rate: subtract the static heart rate (about 60) from the value of 220- age, multiply it by the exercise intensity, usually 50% ~ 75%, and add the static heart rate alone. The numerical range is the heart rate range you should exercise to. In addition, resistance training and stretching training are needed to achieve the best sports effect. Of course, it may not be obvious in the short term, but there will be obvious changes in about 3 months.
