If you're having trouble sticking to your workout resolution because you can never find the time for gym trips, we've got good news: Yoga Tailor, an online service that creates custom-made online Yoga videos for you to use anytime, anywhere.
Once you sign up, you'll have to answer a few questions about your Yoga needs (like what your skill level is, if you have back pain, if you're pregnant, and how long you want your routine to be). From this info, Yoga Tailor creates and streams a personalized video featuring real-life professionals (i.e., no weird avatar instructors), with whom you follow along from the comfort of your own home.
You can always adjust your difficulty or time levels, but even if you keep them stable, the site ensures exercise variety by providing a different workout each time you log in.
The first two weeks of unlimited videos are free, after which you can buy a monthly ($8), yearly ($60) or lifetime ($200) pass--all of which are significantly more economical than a gym you're only half-using.
