Yes4All Olympic Plates Review: Best Budget Cast Iron Plates on Amazon?

Yes4All Olympic Cast Iron Plates are the highest-rated budget weight plates on Amazon. With over 10,000 reviews at 4.6+ stars, they've become the default answer for anyone asking "how do I add more weight to my home gym without spending a fortune?" After 8 months of heavy use, here's our honest review.

Why Buy Extra Plates?

Most home gym starter sets come with 300 lbs of plates — enough for beginners but quickly outgrown:

• Intermediate squat/deadlift: 315-405 lbs
• Advanced squat/deadlift: 405-500+ lbs

Adding two 45 lb plates to your set unlocks another 90 lbs of loading. Adding a full pair set (45 + 35 + 25) adds 210 lbs. At $1/lb on Amazon, Yes4All plates are the cheapest way to expand your capacity.

The Specs

Build Quality

Yes4All plates are solid cast iron with a painted finish. The painted coating is standard for budget plates — it looks good new but will show wear over time. The important part is the cast iron itself, which is dense, accurate, and basically indestructible.

Weight Accuracy

We weighed three pairs of 45 lb plates:

• Pair 1: 44.8 lbs / 45.2 lbs (±0.5%)
• Pair 2: 45.1 lbs / 45.0 lbs (±0.2%)
• Pair 3: 44.9 lbs / 45.3 lbs (±0.7%)

All within ±2%, which is excellent for budget plates. Premium calibrated plates are ±0.1%, but you're paying 5-10x more for the precision. For home gym training, Yes4All accuracy is perfectly fine.

What We Love

What Could Be Better

Yes4All vs Bumper Plates

This is the key decision for anyone adding plates:

Yes4All Cast Iron ($1/lb):

• Cheaper per pound
• Thinner (more fit on the bar)
• LOUD when dropped
• Can crack concrete if dropped

Rubber Bumper Plates ($1.50-2/lb):

• More expensive
• Thicker (fewer fit on bar)
• Safe to drop
• Required for Olympic lifts

Our recommendation: Get cast iron for squats/bench/overhead press. Get bumper plates for deadlifts and Olympic lifts if you need to drop them.

8-Month Durability Report

• Paint: Some chipping on edges (cosmetic only)
• Hole tolerance: Still fits snugly on 2" sleeves
• Weight accuracy: Unchanged
• Any cracks: None, even after thousands of reps
• Rust: None — the paint protects the iron effectively

How Many Plates Should You Buy?

The starter calculation for expansion:

Intermediate Lifter (Deadlift 405+)

• 4x 45 lb plates = 180 lbs added
• 2x 25 lb plates = 50 lbs added
• Total: 230 lbs added to existing set
• Cost: ~$200-230

Advanced Lifter (Deadlift 500+)

• 6x 45 lb plates = 270 lbs added
• 2x 25 lb plates = 50 lbs added
• Total: 320 lbs added
• Cost: ~$280-320

Single Pair Upgrade (Just Need More 45s)

• 2x 45 lb Yes4All plates
• Cost: ~$90
• Benefit: Adds 90 lbs of capacity

Storage Considerations

More plates = more storage. Make sure you have:

• A plate tree or wall rack -- ~$50-100
• Rubber mats under the plates -- prevents floor damage
• Enough wall or floor space -- 8-10 plates takes surprising space

Who Should Buy These?

Buy Yes4All Olympic Plates if:

• You need to expand an existing weight set
• You're on a budget ($1/lb beats $2/lb premium plates)
• You do powerlifting-style training (squat, bench, deadlift)
• You have a rubber floor or lifting platform

Skip them if:

• You do Olympic lifting (get bumper plates)
• You drop weights regularly from overhead
• You need competition-calibrated accuracy
• You have a hard concrete floor without mats

Final Verdict

Rating: 4.5/5 — Yes4All Olympic Plates are the right answer for 90% of home gym owners adding weight to their collection. They're affordable, durable, accurate, and easily available on Amazon. You'll save hundreds of dollars vs premium plates and lose almost nothing in training quality.
