A Tabata workout

Tabata workout is a great conditioning tool that can be done at the end of your workout or as a workout itself. You can include a combination of different types of exercises instead of just using the same exercise through the 8 rounds.. 

For example, you can perform kettlebell (KB) swings and burpees alternately (4 sets/exercise). Doing 2 exercises instead of 1 add variety to the workout and also enable you to perform it at a higher intensity. You can "recover" better for your next set of KB swings while performing burpees and vice versa. In this case, I prefer to start with the tougher exercise first.
