(1) Even so, with bolts and base plates at myriad angles, the steel erector had to maneuver the pieces with hydraulic rams and remove some to fit others in to fine-tune sequencing.(2) So he went to night school to study engineering and became a steel erector .(3) Two of the three divisions of the erector spinae muscle are identified in this cut: longissimus and multifidus.(4) The rectus and the obliques flex your spine, and all of your abdominals, along with the erector spinae muscles of your back, stabilize your spine.(5) The main back muscles involved are the erector spinae.(6) To erect the trusses, the steel erector used twelve 78-ft-tall shoring towers, one under each tip of each cantilever.(7) The steel erector says the frame went together better than expected, but says the success of the job hinged on the ironworkers' dedication and six to eight months of planning.(8) a spinal erector(9) With forward head postures, shortening occurs in the suboccipital muscles and lengthening takes place in the cervical and thoracic erector spinae muscles.(10) Your abdominal and erector spinae muscles isometrically contract to stabilize your torso as you move.(11) The erector then used the trichord's upper chords to support a work platform for the arch.(12) The spine is stable and still, with the rectus abdominis, obliques and erector spinae muscle isometrically contracting.(13) Continue to train abdominals and spinal erectors , as muscle at the front and back of your midsection will distract from your waist width.(14) The officials then went off with ten or so steel erectors to a meeting in a local hotel to try and get them to start work.(15) Throughout the lift, flex your spinal erectors and pull your shoulders back.(16) Depending on the rowing exercise, your spinal erectors may also get into the act.
