I first got “Shred it with Weights,” Jillian Michaels‘ kettlebell workout dvd, about five years ago when I started running regularly so I’d have a strength-training workout to do on my off days from running. I loved the two different workouts on this dvd because they were quick (around 24 minutes each) and each had a great combination of moves. They trick you into thinking they’re easier than they are.

I was excited to find out that Jillian also has a fitness app with a wide variety of workout programs. You can choose from beginner, intermediate and advanced workouts, 30-day or 90-day full programs, 5k training, kickboxing and more. Each individual workout is customized according to your skill level, and you can choose to make future workouts easier or harder once you’re done. Daily meal plans are also included. You’ll also have access to a custom workout generator that lets you choose 10, 20, 30 or 45 minute length, easy, medium or hard workout and where to focus (i.e. abs, total body, arms, chest and back, etc.).

What’s your favorite fitness app or workout?
