This article provides the personal trainer with sample exercise progressions for teaching resistance training movement patterns along with practical strategies for instruction and reinforcement of proper technique.
The primary focus of this article is to provide personal trainers with an evidence- and practice-based approach to exercise selection and implementation in those with low back pain.

From the NSCA 2020 Texas Virtual State Clinic, Erik Korem, Senior Associate Athletic Director for Student-Athlete High Performance at the College of William & Mary, discusses these unprecedented times and safe ways to reintroduce athletes back to full competition.
The purpose of this meta-analysis was to synthesize the literature and provide a robust estimate of the correlations between lower-body, multijoint, isometric and dynamic neuromuscular assessment variables and snatch (SN) and clean and jerk (C&J) performance in competitive weightlifters. A comprehensive search through 3 electronic databases (PubMed, SPORTDiscus, and Web of Science) returned 12 studies that met the inclusion criteria. Meta-analyses were performed on Pearson’s correlations between SN and C&J performance and 15 variables from 5 neuromuscular assessments— countermovement jump (CMJ), squat
jump (SJ), isometric midthigh pull (IMTP), back squat (BS), and front squat (FS) one repetition maximum (1RM). The FS and BS 1RM exhibited nearly perfect correlations (r 5 0.93 to 0.94), whereas the IMTP peak force exhibited very large correlations (r 5 0.83 to 0.85). The IMTP force at 250 ms exhibited very large correlations (r 5 0.77 to 0.78), and the CMJ and SJ peak power exhibited very large to nearly perfect correlations (r 5 0.88 to 0.92). These findings illustrate the importance of lower-body maximal and time-limited force-producing capabilities in weightlifters. Moreover, each assessment offers at least one variable
that exhibits a correlation of .0.70. Therefore, these assessments may be used to gauge weightlifting performance potential.
This excerpt from Exercise Technique Manual for Resistance Training, Third Edition goes over the technique and execution in each phase of the push jerk.
