  • Swiss Ball Jackknife Pike Demonstration of Swiss Ball Jackknife Pike exercise...just a few reps. Some people mistake it for the prone jackknife. For the prone jackknife, your butt doesn't go up in the air like that, your back stays much more flat. You just pull the ball in with your legs toward your chest. The exercise pictured here looks much much harder, so an actual prone jackknife would be easy for you compared to this!

  • Pickup/trailer jackknifes on interstate during snow storm 1:30am, April 6th 2008, 30 miles SE of Fargo ND. Just when we thought spring had arrived, a snow storm reared its head and dumped several inches of slushy snow. I had my camera on and captured a pickup/trailer combination lose control and sink it in the ditch. The snow felt like little rocks on the face at first, but quickly turned to 1" size puff balls-making it hard to see more than 30 feet in fron of me. The pickup/trailer was ok, he just needed to have more than my pickup to pull him out.

  • FedEx truck slams into police cruiser and car I-71/75 Erlanger, Kentucky: FedEx jack Knives into Police Cruiser: as a police cruiser is checking the welfare of occupants of a vehicle that crashed into the median due to icy roads, a second vehicle slams into the cruiser and spins it around into the middle lane facing oncoming traffic. Soon thereafter you can see a FedEx tractor trailer jack knife into the police cruiser. * * * * * * * * * * * * * * * * * * * * * On I-71/75 last night, the freezing rain and snow lent to a horrific scene straight out of a movie in which an out-of-control double tractor-trailer slammed into a helpless compact car. The freezing conditions last night left more than 100000 power customers without power, but it also created the kind of road conditions that led to the crash. With the release of cruiser cam video today, one can now witness sheer terror through the cruiser cam of Erlanger police officer Bill Allen. The events that led up to the disaster were small notes which led to the horrible crescendo. "Both Officer Eagler and I noticed that the road was very slick," Officer Allen told 9News. Just before the crash, Allen and probationary officer Doug Eagler had responded to the scene of a single car spinout. "As we approached the vehicle, we both heard a noise -- turned around and looked -- and saw another vehicle strike the back end of our cruiser," said Allen. The driver in that car was 20-year-old year Ashley Walker, whose bruises now show on her neck her seatbelt restraint. "I seen the ...

  • Wii Fit 30 jack-knives Jack-knives are a super-efficient exercise combining leg lifts and crunches. I started with one set of 10 repetitions and built up to seven sets of 30 on workout days. (But I'm pretty sure you don't want to watch a boring video of 210 reps with breaks in-between!) I'm on my 8th month of using Wii Fit regularly. Haven't had much back soreness since starting jack-knives for "core" training, so it's helped a lot.

  • The Mighty Mighty Bosstones ''A Jackknife To A Swan'' w/ lyrics ''A Jackknife to A Swan'' by The Mighty Mighty Bosstones from the album ''A Jacknife To A Swan'' Lyrics: Shortly after Evelyn Was doused with gasoline And just a few miles off the avenue, A lighter flashed into a puff of smoke. For thirty years Walter worked right there, Five days out of every week, That's where he watched his hometown fade The last came fast and furious. Just step in one direction, Stutter step for one split second, Faster through the intersection, A jackknife to a swan...and he was gone. When Walter's shift was over He'd head out to catch the red line home Two stops away his family slept He'd be there when they got out of bed. Destination subway station, Someone yelled so he looked back Five guys were heading his way He ran to catch that last train home, Just step in one direction, Stutter step for one split second, Faster through the intersection, A jackknife to a swan...and he was gone. Oh Walter ran, and did they kill Evelyn? He had his token in his hand. But he jumped over the turnstile And he ran down the platform They were hot on his heels, An outbound was bearing down on him Walter jumped in front of it. just... Just step in one direction, Stutter step for one split second, Faster through the intersection, A jackknife to a swan...and he was gone. Just step in one direction, Stutter step for one split second, Faster through the intersection, A jackknife to a swan...and he was gone.
