The Log

One of the most amazing teaching tools is know as - the log. Its made from 100% log. You can carry it around (see picture) as a team and be forced to do various exercises- sit ups, squats, push ups, you may even have to carry someone around. It can be carried over all kinds or terrain-land water,throguh the brush, uphill, downhill.
You can even use it as a bridge over water and walk across it blindfolded. Rumor has it some have even sparred against their partner while blindfolded on the log.
