Circuits are now a part of your training program, with at least one session a week devoted to circuit training, adding challenges and increasing your cardiovascular workout.
Some clients have reported they enjoy the variety and intensity of the workouts, while for others, the "not having to think about what to do next" is most appealing.
Whether you love them or not, you are gaining multiple benefits from your circuit workout, including an increased general working capacity by improving your ability to tolerate increasing levels of muscular fatigue, maintain elevated heart rates during the workout and helping you to upgrade your cardiovascular capacity - stamina improvement.
Circuit will also enhance your overall body strength including the strength and resilience of muscles, tendons and ligaments, the integrity of your joints and the strength & density of your supporting bone structures - strength improvement.
The circuit will improve your skill and body awareness because you'll perform exercses that utilise body weight as the primary form of resistance - skill improvement.
You will also increase your lean muscle mass by a moderate amount and decrease your body-fat levels through high levels of energy expenditure -body composition improvement.
I strongly recommend you use your periodisation plan, do your 30 minutes cardio as scheduled, rest on your rest days to allow your body to be at it's best for your next training session.
Ditch those takeaways, high-calorie, low-nutrient foods and keep up the GREAT work!
