I use a yoga mat when I do Insanity workouts and hate it when it slips and slides during power jumps, burpees, or other plyometric movements. The guys at Gurus are out on Kickstarter with a no-slip, natural yoga mat made of cork. Natural cork and rubber repels moisture, making a non-slip surface that also has anti-microbial benefits. It’s easy to clean and can also be used on both sides. The mats are also made as a sustainable product, harvested by hand from trees through a harmless process. Starting at $70 on Kickstarter you can get the Guru Roots cork mat with a free yoga mat bag. You’ll be saving $55 off future tail price, so check it out on Kickstarter now.
