High intensity interval training (HIIT) has become very popular recently. Whether it’s knocking out sprint intervals on the track or cycling or strength and resistance training circuits that feature built-in rest periods are great for burning fat while building strength, power, endurance and cardiovascular health.
Truthfully, they are challenging and can lead to injuries and over training if not approached correctly.
A great alternative is rest-based interval training. But rather than watching a timer you actually tune into your body. It is more individually tailored and you rest according to how you feel not what a clock says. As opposed to HIIT you rest between circuits or sets as needed.
Bottom Line: Workout until you cannot and then rest until you can. This approach builds fitness and stamina witnout leaving you trashed.
