Here are some possible methods:

1. Cross-arm swing: This is a common and simple step training method. When walking, cross your arms in front of your chest and swing them alternately from side to side. This helps the team maintain rhythm and alignment.

2. Kicks and spins: While walking, you can perform some simple kicks and spins, which not only adds fun, but also improves coordination and teamwork spirit.

3. Design formations: You can design some interesting shapes or patterns, such as animal shapes, letters or numbers, etc. This will make the procession more enjoyable to watch as it walks.

4. Music coordination: Choosing music that suits the walking rhythm can make the team walk more orderly. At the same time, music can also help team members relax and improve training efficiency.

5. Train different steps: In addition to ordinary steps, you can also train some special steps, such as "Z" steps, wave steps, etc. These steps require the tacit cooperation of the team members, but they can bring different effects during performances.

6. Use passwords: During training, you can shout passwords to help players stay in sync. For example, "left-right-left-right-", or "one-two-one-two-". This can help players better control the rhythm of their steps.

Some of the above methods may take some time and patience to master, but once mastered, you can produce a very exciting square performance.
