Variable resistance curves, joint stress, and the science of muscle activation.

Ascending vs Constant Resistance
Free weights = constant resistance. Bands = ascending (harder as they stretch). Research from the Journal of Strength and Conditioning: bands produce comparable muscle activation for many exercises, but patterns differ. Bands maximize tension at full extension; weights maximize it at the stretched position.
Real Answer
Bands don't replace heavy compound lifts. They're superior for rehab, travel, accessory work, and combining with barbells for accommodating resistance.
Pre-cut loops, latex-free, used by physical therapists. Best for rehabilitation.

Frequently Asked Questions
Can resistance bands build muscle as effectively as free weights?
For beginners, bands can produce similar gains. For intermediate+ lifters, free weights are superior due to consistent loading and progressive overload capability.
What resistance bands should a beginner buy?
Start with a set of loop bands in 3-5 resistance levels ($15-30). Mini bands for lower body activation ($8-12) are also valuable.
Do resistance bands wear out?
Yes. Latex bands last 6-12 months of regular use. Inspect before each use for nicks or thin spots. Replace immediately if damaged.
