Last time you straddled a tree, the neighbors called the police. But with the TreeYoga Multi-Sling, only your panties will be tied in a knot.Created by local school teacher and yoga instructor Hal Pruessner, the device is for beginner to advanced yogis wanting to practice closer to nature. The kit comes with a backpack, padded industrial-strength body slings, and an unpadded one for looping around a sturdy tree trunk or limb. There’s also an instructional DVD with an easy-to-follow session (postures are both suspended and on the ground) as well as a how-to for safely fastening the sling. Bonus feature: Since gravity tugs on your body during the limbtastic moves, stretches are more intense, making you stronger and more limber. Neighborhood Watch, look out.
