FAQ

What’s the difference between Olympic and standard plates?

Olympic plates have a 2-inch center hole and fit modern barbells and racks; standard plates use a 1-inch hole. Most home and commercial-style setups use Olympic plates for the best compatibility.

Should I choose bumper plates or iron plates?

Bumper plates are designed to be dropped and reduce noise and floor impact, while iron plates are thinner and ideal if you’re not dropping the bar. REP Fitness offers both styles; see our guide comparing bumper vs iron plates.

What weight plate set is good to start with?

Pick a mix that covers your main lifts and allows small jumps—commonly pairs from 10–45 lb (or 5–25 kg) plus change plates, then add more 45s/20s as you progress. For a step-by-step approach, check our guide to picking the best weight plates for your gym.

What are calibrated steel plates and who are they for?

Calibrated steel plates are thin and precision-weighted, so you can load more on the bar with tight accuracy—great for powerlifting or competition prep. REP’s calibrated options are available in both LB and KG to match your programming.

Do I need fractional or change plates?

They’re not essential at first, but fractional/change plates let you make smaller, consistent increases—especially useful for bench and overhead press as you near plateaus. Many lifters add them once progress slows for more precise loading.
