If you’re anything like me, finding the time to go to the gym during the week can be nearly impossible. I tell myself every night before going to bed that I’ll get up early to run on the treadmill, but usually I end up snoozing my alarm five times. I also tell myself every morning before going to class that I’ll do strength training later, but usually I end up putting my pajamas on instead. Despite my weekend-only gym attendance, working out is part of my daily routine.

One of my high school friends introduced me to Blogilates, a revolutionary website and YouTube channel full of resourceful workouts tailored to specific goals. With almost four million subscribers, founder Cassey Ho has transformed the face of online exercise videos. They’re short, energizing and more difficult than you’d think. The best part is that I can do them in the comfort and privacy of my own dorm room. Using a cushy yoga mat, I’ll knock out a solid 45-minute workout in between classes when I’m tight for time.

In case you’re skeptical, check out this list of my favorite videos. To get the most out of your workout, my advice is not to pause the video and take breaks. You must have a certain level of self-control to continue the video even when your abs are on fire. But trust me, the temporary pain is worth it.
