Functional 4.0 is a popular high energy training class that builds intensity continuously over the 50 minutes. Group training is a great way to add extra motivation. Within this class you will train eight different functional exercises, each for 50 seconds and completing four rounds with minimal rest. Increase your reps and/or weight each round to push yourself to the next level. No class is ever the same, you will also combine cardiovascular and functional strength exercises to get the results you want.
