What Do Resistance Band Tension Levels Mean?

Resistance bands are graded by the amount of pulling force needed to stretch them, usually shown as a weight range (or colour-coded by brand) rather than an absolute standard across manufacturers. Lighter bands suit rehab, warm-ups or beginners, while heavier bands suit strength training — many sets are sold in graduated packs so resistance can increase as strength improves.

What Does Thickness (mm) Mean for Yoga Mats?

Yoga mat thickness, usually 3-6mm for general use, is a trade-off between cushioning and stability: thinner mats (around 3mm) give better balance and floor contact for standing poses, while thicker mats (5-6mm+) cushion knees and joints better for floor-based or restorative practice. Travel mats are typically thinner still, prioritising low weight and pack size over cushioning.
