Large muscles like the back, glutes and thighs suit a foam roller; feet and the spots between the shoulder blades suit a massage ball; a stick works the legs without getting on the floor; a strap holds stretches you cannot reach. This tool asks what you want to work on, the pressure you like and whether the tool travels with you, then names the 321 STRONG product that fits and the alternatives worth a look. For rollers, our position is that texture and density matter more than extras like vibration, and medium density suits the majority of people.

## Frequently Asked Questions
   
### What is the difference between smooth and textured foam rollers?
 Smooth rollers spread pressure evenly across the muscle. Textured rollers use ridges, knobs, or multi-zone patterns so some parts press harder than others, which makes it easier to work one tender spot without changing tools. 321 STRONG's patented 3-zone texture gives narrow ridges, finger-like nubs and a flatter zone on one roller. Every roller in the 321 STRONG range is textured.

  
### Are vibrating foam rollers worth it?
 Studies disagree. Trials comparing vibrating and plain rollers have mostly found small differences in soreness and flexibility between them. 321 STRONG's view, from years of making rollers: texture and density change how a roller feels far more than vibration does, and a plain roller has no battery to charge or motor to wear out.

  
### What foam roller density is best for beginners?
 Medium density is the right starting point for nearly everyone. Very soft rollers flatten under body weight, so you feel less pressure. Firm rollers are often too uncomfortable for people new to rolling to relax on. Medium density gives clear pressure that most beginners can stay on for a full minute.

  
### How long do foam rollers last?
 A well-made closed-cell foam roller keeps its shape for years of regular use. Low-density open-cell foam can flatten within months under repeated loading. 321 STRONG rollers use closed-cell EVA or EPP foam that holds its shape. If your roller has visible flat spots or soft patches, it is time to replace it.

  
### What size foam roller should I buy?
 A roller around 12-13 inches long is the most versatile size: it handles calves, quads, the outer thigh and the upper back, and it fits in a gym bag. Longer rollers are easier to balance on for back work and for lying along the spine. All of the 321 STRONG single rollers are the shorter, more portable length.
