You can join friends with similar physical conditions to exercise together, but don't run in groups every day and force yourself to keep up with others. But it is ok to participate in group activities with moderate exercise, such as yangko, group dance and group gymnastics. Combine exercise with interest, exercise with one's own conditions.
