We’re doing a 12-hour tie job next week with a five-man gang, lots of lining bar work and plates in 90° heat — anyone have a simple 5–10 minute warmup that keeps backs and hamstrings from locking up without slowing the lineup? If you’ve got a printable card or quick video we can run in the lot before callout, drop it — works best if it’s doable in steel toes and vests.
On our 12‑hour tie jobs, the one thing that’s stuck is a 90‑second hip‑hinge using the lining bar as a dowel — hold it along your spine and cue ‘three points: head, mid‑back, tailbone; hips back until you feel the hamstrings, then squeeze up’ for about 15 slow reps in steel toes. If the lot’s chewed up, face a truck and tap the bumper with your butt so you don’t tip. I can post a simple one‑pager for the lot if you want.
