The two videos I have place below deal with stretching and core exercise which are two extremely important places (in addition to cardio) to build a foundation for future health and fitness achievements.
Stretching helps to warm your body up and lessen the likelyhood of injuries and the impact of the workout.
Core exercises are important because your core is utilized in almost every exercise whether you feel it or not.
Suggestion - Do in the comfort and privacy of your home to get decent at these... I tried at the gym and its difficult, if your not used to it.
