Free HIIT Short Video Exercise Programs to Improve Legs & Core Strength

Here are short videos to inspire you to get stronger legs and core. Each HIIT video demonstrate easier to harder options and from low to high impact cardio exercises.

Do each exercise for 30 to 45 seconds with 10 seconds rest. Go to the next exercise (same short video). At the end of the set, take between 30 to 60 seconds rest and begin the second short video. If you want a longer workout, repeat the same video twice and switch legs in necessary.

I have created the Follow Along versions and you can get them here.

Have fun!
