40 Minute Brutal HIIT Cardio and Kettlebell Workout

Looking for a challenging workout? This one definitely delivers!

40 Minute Brutal HIIT Cardio and Kettlebell Workout - Workout to Build Lean Muscle and Burn Fat Fast.

Including a very thorough warm up and cool down, the entire routine is under 45 minutes, but still provides a serious cardiovascular and strength challenge.

You might find yourself coming back to this routine whenever you don't have a lot of time, but really want to push yourself and get the most done in the least amount of time.

Anyway, give it a try and let us know what you think. Did you find it difficult? Did it give you the burn you wanted?

Pro Tip: Want to make this one even harder? Well, there are a few things you could do: check your form (if it feels easy, you're likely doing it wrong), lift heavier weights, move faster, contract your muscles to work "against" yourself the entire time, do higher impact exercises during the rest intervals, wear a weighted vest, or use a deeper range of motion (for jumps, squats, lunges, etc).
