Getting into the habit of exercising can be hard, especially if you're not used to it. When you are out of shape, or not as frequent at the gym, even running on the treadmill for 10 minutes can seem like a crazy idea. Conclusion? It is very hard to get back into exercising, or if you're new at it, just finding a way to begin. Here are five fitness guru's that can help you get back on track through their ideas, motivations, and challenges.

Kino MacGregor is an international yoga teacher, author of three books, traveler and co-founder of Miami Life Center. She also is the co-founder of Miami Yoga Magazine. MacGregor has been practicing Ashtanga Yoga, or "eight-limbed" yoga, for 15 years, and posts inspirational videos and photos on her social media every day. Because she is constantly traveling, MacGregor uses technology to bring her passion for the practice to everyone. Her online classes can be found on the Cody app, YouTube, her blog and her books.

MacGregor also offers a fun way for followers to get involved in yoga through monthly challenges. Each challenge focuses on a different part of the body and provides instructional videos on Instagram for each day. What is best about these challenges is that MacGregor describes how to properly get oneself into the poses so well, that you might as well be in a class. Because she practices the fourth series of Ashtanga, the moves she offers can be advanced. Fortunately, MacGregor provides directions for different levels of the pose so that everyone is able to participate. Currently, MacGregor is hosting her February Instagram challenge, #MonthofMeditation, with friend Kerri Verna.

Karen McLean is a food blogger and brand ambassador living in Dubai. Originally from Australia, McLean was inspired to start her blog on simple and healthy eating when she moved to the Middle East and was unable to find a lot of healthy food options. After starting the blog, it is McLean's goal to spread her love of healthy eating throughout the Middle East. With 123k followers on Instagram, she is accomplishing her goal.

Although she is passionate about healthy eating, McLean also understands that the idea of "clean eating" can connote an aura of "high maintenance."

Recent recipes featured on her Instagram include sesame cookies, gluten-free banana coconut pancakes and coconut vanilla chia pudding with pomegranate and raspberries.
