It is best not to skip rope in the morning, because the muscles are just awake in the morning, and the knowledge of skipping rope only increases the vital capacity. It's easy to faint after exercising around 9 o'clock in the morning. Skipping rope at noon is the best, because muscles are more active at that time, and exercise at noon is better. As for yoga, I won't practice it. Just keep fit and do aerobic exercise first. Practicing yoga can easily lead to bone damage.
