Bowflex 552 vs PowerBlock Pro EXP — Head-to-Head Comparison

If you’ve researched adjustable dumbbells for more than 15 minutes, you’ve encountered two names: Bowflex SelectTech 552 and PowerBlock Pro EXP.

These are the two most popular adjustable dumbbell systems in the world, and they could not be more different. One uses a rotating dial and looks like a traditional dumbbell. The other uses a selector pin and looks like a black box with a handle sticking out.

This head-to-head comparison breaks down every dimension that matters so you can decide which one belongs in your home gym. Check out our complete adjustable dumbbells comparison to see how these stack up against the rest of the market.

Weight Range & Progression

Bowflex 552: 5–52.5 lbs per hand. Increments are 2.5 lbs from 5 to 25 lbs, then 5 lbs from 25 to 52.5 lbs. The range is adequate for beginners and most intermediate lifters. The 2.5-lb increments in the low-to-mid range are excellent for progressive overload. A 180-lb male lifter can expect to outgrow 52.5 lbs for pressing within 12–18 months of consistent training. For isolation exercises (lateral raises, curls, tricep extensions), 52.5 lbs is effectively permanent — you simply won’t need more for those movements. The 5-lb jumps above 25 lbs are standard but noticeable when you’re dialing in your working weight.

PowerBlock Pro EXP: 5–90 lbs per hand (with both expansion stages). Increments are 2.5 lbs from 5 to 25 lbs, 5 lbs from 25 to 50 lbs, then 10 lbs from 50 to 90 lbs. The 10-lb jumps at the high end are the biggest drawback — missing your ideal training weight by 10 lbs is noticeable, especially for pressing. However, 90 lbs per hand covers every home gym user except elite powerlifters. For context, a 200-lb lifter benching 275 lbs with a barbell would dumbbell press roughly 80–90 lbs per hand — right at the ceiling.

Winner: PowerBlock — 90 lbs vs 52.5 lbs is not close. The coarser increments at high weight are a real limitation but a manageable trade-off for nearly double the weight capacity.

Adjustment Speed

Bowflex 552: Place the dumbbell back in the cradle, rotate the dial to the desired weight, lift. Total time: 2–3 seconds per dumbbell when the dial clicks perfectly. In practice, dials sometimes overshoot or land between settings, requiring a correction. Real-world time: 3–5 seconds per pair. This is fast enough for traditional strength training where you change weight every 3–4 sets. For circuit training, the cumulative downtime adds up.

PowerBlock Pro EXP: Place the dumbbell on the tray, pull the selector pin out, insert it into a different slot, lift. Total time: 0.5–1 second per dumbbell. The pin slides in and out with one smooth motion. This is one of the fastest mechanisms in the adjustable dumbbell category. In a circuit training workout with 8 exercises and weight changes between each set, PowerBlock saves about 30–60 seconds of total workout time compared to Bowflex. In a traditional strength session with 6 exercises and 3–4 sets each, the difference is about 20–30 seconds — meaningful for circuit trainers, negligible for strength lifters.

Winner: PowerBlock — faster by a clear but context-dependent margin.

Durability

Bowflex 552: The Bowflex 552 has known durability issues. The most common complaints include the dial mechanism jamming (internal ratchet can seize, especially if dropped), the plastic cradle cracking under heavy use, weight plate wobble (metal plates with plastic housings that wear down over time), and decals fading and peeling. On the positive side, replacement parts are widely available and reasonably priced. Bowflex’s customer service is responsive for in-warranty issues. Lifespan estimate: 3–5 years of regular home use before issues emerge.

PowerBlock Pro EXP: The PowerBlock Pro EXP is built like a tank. The main body is a solid block of steel weight plates nested inside each other. There are no dials, no gears, no plastic weight housings. The selector pin is the only moving part, and it’s beefy enough to withstand years of abuse. The steel plates will never crack, warp, or wear out. The selector pin is replaceable ($15) if lost or damaged. The handle foam can compress over years of use but is also replaceable. Lifespan estimate: 10–20+ years. These can be handed down to your kids.

Winner: PowerBlock — significantly more durable. Not even close.

Feel & Grip

Bowflex 552: The handle is 1” in diameter with a contoured rubber grip. It feels good in the hand — similar to a standard dumbbell handle with a bit more padding. The rubber provides decent grip even with sweaty hands. The dumbbells maintain a traditional shape: handle centered, plates evenly distributed on both sides. This means they feel natural for all exercises — pressing, rows, curls, lunges, and especially goblet squats and renegade rows where you grip the bell end. The bell shape at each end is comfortable when resting on thighs during seated exercises like incline curls or hip thrusts.

PowerBlock Pro EXP: The handle is a solid steel rod, about 0.75” in diameter, wrapped in a thin rubber or foam sleeve. Some users love the thin handle (easier to grip for people with smaller hands, better hook grip for pulling). Others hate it — less surface area means more pressure on the palm during heavy pressing. The rectangular block shape is not ergonomic for everything. The block can dig into your thighs during seated exercises. Goblet squats require awkwardly gripping the block itself. Renegade rows are practically impossible. However, for pressing, rows, and overhead work, the block shape isn’t an issue — you only touch the handle, and it feels fine.

Winner: Bowflex — more natural and versatile across all exercise types.

Noise

Bowflex: The dial mechanism makes a distinct clicking sound during weight changes. During lifting, the plates are relatively quiet — some minor metal-on-metal noise, but nothing excessive. The plastic cradle can creak under load if there’s any wear. Overall noise level: moderate. Noticeable but not disruptive in an apartment setting.

PowerBlock: Weight changes make a single metal click when the pin engages. During lifting, the nested plates can rattle slightly, especially at higher weights (60+ lbs). The noise is metallic and sharper than Bowflex’s low thud. Overall noise level: low to moderate. Quieter than Bowflex for weight changes, slightly louder during heavy sets due to plate rattling. Both are acceptable for apartment use.

Winner: PowerBlock — marginally quieter overall. The difference is small.

Storage Footprint

Bowflex 552: The cradle measures roughly 16” × 16” × 6” when both dumbbells are nested. Total footprint: about 2 square feet. The cradle is a fixed piece — you can’t fold it or break it down. It’s designed to sit on a shelf, countertop, or dedicated stand. The dumbbells themselves don’t sit on top of the cradle; they’re stored within it, which means the footprint is all base with no additional vertical space.

PowerBlock Pro EXP: The base tray measures roughly 12” × 8” × 4” for the 50-lb set. That’s less space than a pair of running shoes. With expansion kits, it grows to roughly 16” × 10” × 6”. The dumbbells sit on top of the tray when not in use, adding about 8” of height. This is the most storage-efficient adjustable dumbbell system on the market. The 50-lb configuration can fit on a closet shelf, under a bed, or in a drawer.

Winner: PowerBlock — significantly more compact, especially at the 50-lb configuration.

Price

Bowflex 552: ~$350 retail, one-time cost. No expansion available. ~$6.70 per pound.

PowerBlock Pro EXP: ~$400 base (50 lbs). ~$110 per expansion stage. ~$620 fully expanded (90 lbs). At full expansion, ~$6.90 per pound — virtually the same cost per pound as Bowflex, but with 70% more weight.

Winner: Bowflex for upfront cost. PowerBlock for long-term value per pound.

Warranty

Bowflex: 2 years frame, 1 year parts. Short for this price point.

PowerBlock: 5 years frame, 1 year decals. Significantly better.

Winner: PowerBlock — 5-year vs 2-year frame coverage is clear.

The Verdict

Overall: PowerBlock Pro EXP wins 7 categories to 4.
