There's very little in life that is more relaxing than standing on your head.

At the beginning of this new century, yoga has replaced jogging as the perfect workout. Both a muscle toner and mental tonic, yoga leaves you relaxed and present.

You wouldn't want anything to spoil your yoga practice - such as the nagging suspicion that the mat you're on is a product of activities you heartily disapprove of. So why not make sure it isn't? Your nearest search engine can point you in a thousand different directions (green yoga is definitely a growing industry), but as a starter, here's BareFootYoga’s mat, a personal favorite of mine.
It's the original, award-winning eco mat made of natural rubber and jute ($67-71.95).

Since rubber does contain latex, if you're allergic, an eco-conscious alternative I recommend is the Earth Elements yoga mat ($38.95-42.95). Or choose the Jute and PER mat, a latex-free, decompostable, machine-washable $39 deal. Next up, persuading your yoga studio to do an eco-friendly overhaul, as this yogi did by filling the walls of his studio with recycled denim!
