I usually get my cardio training outside of my 2 a week gym sessions, which consist of strength and conditioning training, in the form of full court basketball, and or solo basketball drill session, and or hiking or outdoor family activity.  After a gym session the previous evening I felt motivated to do the following bonus cardio gym session this evening.  It went as follows:

• Cycle long distance interval circuit (15 min total)
• Stretch cage session (total body)
• Treadmill long distance interval circuit (12 min total)
• Yoga palates circuit (total body)
• Cycle long distance interval circuit (10 min total)

(37 min total of cardio and entire session a total of 1 hour)
