Warm-Up: Upper-Body Activation

Before you load a barbell or grab a pull-up bar, your upper body needs a signal that work is coming. Warm-Up: Upper-Body Activation is Flexor's readiness routine to raise temperature, open key joints, and prepare you to move well through pressing, pulling, and overhead patterns.

What you will move through

This sequence activates the upper back, shoulders, and core so pushing and pulling mechanics feel stable from the first rep. You flow from neck circles and shoulder rolls into overhead reach and dynamic chest flys, then layer in wall arms, wall plank, upward dog, and wide-leg side bend — a chain that touches neck, shoulders, upper back, chest, core, and glutes without any equipment.

• Neck and shoulders first: Small circles and rolls wake up the area above your collarbone before bigger ranges.
• Dynamic chest work: Controlled flys and overhead reach prime the chest and lats for load.
• Core-aware holds: Wall plank and upward dog connect trunk stability to arm movement.

Who this fits

Beginner-friendly and built for strength prep, this warm-up suits anyone heading into upper-body training who wants stable mechanics rather than rushing into heavy sets. Flexor paces each transition so you can focus on quality over speed.
