The PowerPull, Chuck Vogelpohls latest creation will absolutely help strengthen your back. One function will start with the bar close to you and as you make your pull, the bar travels farther away from you strengthening the upper back and lock out. Flipping the PowerPull over, starting out with the bar father away from you and pulling close will strengthen the lower back, helping create that locked in positioning you need for the start of the deadlift. This product has a 1-3 week lead time depending on how many orders we have to complete, times may run longer.
