What are PAILs/RAILs??

Summary

Key Points

• —Pails and Rails, standing for Progressive Regressive Angular Isometric Loading, is a technique that utilizes isometrics in two directional inputs to expand range of motion and increase the strength and resilience of tissues. 0:14
• —The primary reason for tightness in a range of motion is often weakness, as the nervous system protects against potential injury by limiting movement, which Pails and Rails aims to address by strengthening those ranges. 1:39
• —The method begins with a two-minute passive stretch to open up more passive range of motion, followed by isometric contractions to strengthen the newly acquired range. 3:32
• —Intensity should be gradually built up, starting low (e.g., 10-20% of max effort) especially for new practitioners or those with pain, and never pushing through sharp pain, only discomfort. 5:42
• —The 'Pails' (Progressive) contraction involves slowly driving force into the lengthened tissue (e.g., hamstrings in hip flexion) for about 20 seconds, gradually building up tension to a chosen intensity. 6:23
• —The 'Rails' (Regressive) contraction is a quick transition from Pails, where force is applied by attempting to lift the limb, engaging the shortened tissue (e.g., hip flexors) for about 15 seconds at the same intensity. 7:11
• —Cramping during the Rails contraction indicates neurological confusion and should be addressed by lowering intensity or slowing the transition, as control will improve over time. 7:50
• —Typically, two to three rounds of Pails and Rails are performed, with a 45-second passive recovery period between rounds to allow the nervous system to reset. 8:50
• —Pails and Rails can be applied to various joints and positions, helping individuals identify and strengthen their specific areas of limitation, which is considered a powerful form of functional strength training. 11:03
• —For hyper-mobile individuals, the focus shifts from increasing passive flexibility to strengthening the existing range and closing the gap between active and passive range of motion, with less emphasis on the initial passive stretch. 12:32
