Squat And Hinge Range
The hip and knee positions used in squats, deadlifts, hip hinges, and similar lower-body work.
Example: leggings that stay covered at the bottom of a squat.
Why it matters: seat fabric, thigh openings, and waistbands are under the most stretch here.
Watch for: fabric sheerness, waistband rolling, or shorts binding at the hip crease.
Overhead Reach
Arm positions that lift the shirt, sports bra, or jacket while the shoulders move above the head.
Example: a training top that stays down during an overhead press.
Why it matters: short hems and tight shoulders can expose the torso or restrict the press.
Watch for: sleeves pulling, hems riding up, or neckline shifting.
Rotation And Twisting
Movements where the torso, hips, or shoulders turn while the clothing tries to stay in place.
Example: a top that does not twist around the waist during medicine-ball rotations.
Why it matters: rotating fabric can pull seams into pressure points.
Watch for: side seams drifting or waistbands turning.
Lateral Movement
Side-to-side movement such as lateral lunges, skaters, shuffles, and agility drills.
Example: shorts with enough side opening for a lateral lunge.
Why it matters: many garments stretch forward and back better than they stretch sideways.
Watch for: hem restriction, inner-thigh bunching, or brief coverage gaps.
Garment Recovery
The ability of fabric and elastic to return to shape after being stretched by repeated reps.
Example: tights that do not sag after several squat sets.
Why it matters: poor recovery can make clothing slide, bag, or lose coverage during the workout.
Watch for: knees bagging out or waistbands loosening mid-session.
Coverage At End Range
Coverage when the body reaches the deepest, widest, or highest position in an exercise.
Example: a shirt that still covers the torso at full overhead reach.
Why it matters: end range is where fit problems usually appear first.
Watch for: gapping, transparency, riding up, or tugging between reps.
Tip: Judge each garment in motion, not only by size, fabric label, or mirror fit.
