Set an interval timing app to time five intervals of 30 seconds work and 30 seconds rest. If you're doing the workout without a partner, you'll be pushing yourself as hard as possible during the 30-second work period, then resting during the 30-second rest period. If you're working with a partner, you'll simply switch off, one of you doing your work during the work interval, and the other doing your work during the rest interval:

The only way to stop your opponent in a fight is to inflict enough damage so he is incapable of further aggression. This means you have to know what anatomical targets are available for you to attack in a fight. This is actually important form both offensive and defensive reasons. Essentially, this means you have to assailant's anatomical targets are located in one of three possible target zones.

The ALACTIC system (aka the phosphagen or phosphocreatine system) is the energy system capable of producing the most energy within the shortest amount of time. A fight-ending flurry or combination uses this energy system. The alactic system is different to the aerobic and anaerobic system in that it produces energy by directly breaking down the ATP molecule, bypassing the conversion of fats, carbohydrates or protein into ATP. However, our body has limited stores of ATP, therefore the alactic system is the quickest to fatigue and can only produce large bursts of energy for up to 10 seconds. Fully restoring phosphocreatine and ATP stores takes around 5-8 minutes; this restoration time can be influenced by strength & conditioning training, as well as the level of development of the aerobic and anaerobic system.
