Complex technical movements: Some skipping movements require high skills, such as cross jumping and back flip. These movements need more practice and time, and are not suitable for short-term rest, which may easily lead to students' injury or great sense of failure.

High-difficulty jumping combination: High-difficulty jumping movements such as continuous cross jumping with two feet and continuous jumping with one foot need high balance and control ability, which is not suitable for such a short time between classes.

Actions that need more space: such as turning around and jumping back and forth. These actions need wider space to ensure safe and smooth completion, and there may not be enough space during the big recess.

Weight-bearing repetitive movements: For beginners or students with poor physical fitness, some weight-bearing continuous rapid jumping movements, such as rapid continuous jumping of feet or crossing of feet, may lead to fatigue and discomfort.

Skipping rope during the big class, you don't need much skill to choose a relatively simple and safe skipping action. For example:

Basic single jump: By mastering the skills of single jump, you can improve the basic skills of skipping rope and promote body coordination and cardiopulmonary function.

Jumping with both feet alternately: Simple jumping with both feet alternately can increase the difficulty of skipping rope, but it is not too complicated and suitable for large classes.

Simple jump: simple jump rope jump, such as jumping once and continuing single jump, can improve the difficulty while maintaining relative safety.

Skipping rhythm exercises: You can design some simple rhythm exercises, such as adding simple melody, changing the rhythm of jumping, and making skipping activities more interesting.

Generally speaking, skipping between classes should pay attention to safety, adaptability and fun, choose simple and easy-to-master movements, encourage students to participate, avoid overly complicated or risky movements, and ensure that all students can participate in and enjoy the activities.
