Fitness Center Circuit Workout

Cardio and your weight machine workouts
You should ideally begin every single workout with
a bit of cardio in order to warm up your muscles.
10-15 Minutes is sufficient for prepping your
muscles for more demanding physical activity (like
the circuit training workouts above).
On the days where you only do cardio workouts,
aim for between 30 and 60 minutes of at least a
5/10 perceived exertion level. Always make sure to
stretch your muscles when you finish workouts,
especially when doing a strength training routine;
the damage caused by the ripping of the muscle
fibers can cause them to bind and tighten up.
