I have always poked fun at this kind of stuff, even the snobungees.....but as I get older and have now been through 2 back surgeries, I hate to say it but I will be carrying a snobungee and I can see the day coming that I will need to carry one of these jacks . I can still lift a sled if I have to....BUT, lifting will likely shorten the years I will be able to ride actively....so my choice will be to use things that will extend my riding years.
EXACTLY. I'm only 32 but yanking on sleds for 20years and lots of other back wrenching activities has screwed my back up pretty bad.
To the guy who does power lifts in the summer so he can yank on a sled in the winter.....you'll be in my shoes soon....make sure you have insurance that covers chiropractors and physical therapy.
