Welcome to Week 3 of The Globe and Mail's Summer 2012 Boot Camp.
Click here for a complete rundown of the program – including what equipment you'll need, how many reps you should be doing and how to choose your cardio activity. And if you're just joining us, head there for the previous weeks' workout instructions.
Remember to always check with your doctor before starting a new fitness routine.
Week 3: Get fit faster with cardio intervals and a resistance band
Beginner and advanced: Do the workout three times a week, on non-consecutive days. Do each of the weight circuits three times though.
Beginner: In the middle cardio segment, do the lower end of recommended intervals.
Advanced: In the middle cardio segment, do the higher end of recommended intervals.
Remember, intervals are relative to your fitness level. If you are a beginner, your "fast" interval may be walking at a slightly higher speed. If you are advanced, your "fast" interval may be an all-out sprint. Work at your personal fitness level.
