Ok, one holiday down, a couple more to go. The holiday season is definitely a challenging time to try and keep to healthy eating and lifestyle changes. Making sure to keep active is very important so here is a high intensity workout you can do that will surely kick your ass!
H.I.I.T - High intensity interval training is a great way to get a very challenging workout even if you don't have a lot of time. This type of training involves periods of intense work followed by periods of recovery and is strongly associated with weight loss, improved cardiovascular endurance, and improved athletic performance.

H.I.I.T. isn't for everyone. If you have any heart issues, high blood pressure, or joint problems ,such as arthritis, consult your doctor before performing exercise like this.
