The short version: if you already know you will train regularly, buy the Bowflex SelectTech 552 — it reaches 52.5 lb per hand, changes weight with a fast twist of the dial, and is the set most beginners should just get. The 5-in-1 25 lb set earns its place in exactly one situation: you are on the tightest budget, or you are not yet sure home lifting will stick, and you want the cheapest possible way to find out. It is the low-risk test; the Bowflex is the buy-once answer. Here is the full comparison.
The quick verdict
Buy the Bowflex 552 if you are reasonably sure you will keep training — its 52.5 lb ceiling and dial adjustment make it the set you will not need to replace. Buy the 5-in-1 if money is genuinely tight or you want to prove to yourself that you will actually use dumbbells at home before spending more. Both build strength equally well at the light end; the difference is how far each can take you and how confident you are today.
Meet the two sets
The 5-in-1 adjustable set is a sub-$120 pair that tops out at 25 lb per hand and comes with a storage tray. It uses quick-lock plates to change weight, and it is the lowest-cost route into any adjustable pair. That low price is the whole point: it is the least you can spend to find out whether training at home is a habit you will keep. The catch is a 25 lb ceiling and a generic brand, so it is best treated as a starter rather than a set you keep forever.
The Bowflex SelectTech 552 is the dial-adjust benchmark: one dumbbell replaces fifteen, from 5 to 52.5 lb per hand, in a footprint the size of a shoebox. You twist the dial to select the weight, the 5 lb floor suits a true beginner, and the whole thing is compact enough for an apartment. It is the set most buying guides — including ours — put at the top, because it does the core job better than almost anything at the price.
Weight range: 25 lb vs. 52.5 lb
This is the difference that matters most. The 5-in-1 caps at 25 lb per hand; the Bowflex runs to 52.5 lb per hand. Twenty-five pounds covers the early days of light upper-body work, but it runs out quickly on the lifts that get heavy fastest — goblet squats, rows, lunges. Most people press past 25 lb within a few months. The Bowflex's 52.5 lb ceiling, by contrast, outlasts a beginner's first year or more, which is exactly why it is worth more. If you want to see realistic numbers before deciding, our starting weight guide lays them out by exercise.
Adjustment and convenience
The Bowflex changes weight with a twist of the dial — quick, clean, and about as fast as adjustable dumbbells get. The 5-in-1 uses quick-lock plates you add or remove, which is slower and more hands-on. For simple set-and-lift training, the 5-in-1's slower swaps are a minor annoyance, not a dealbreaker. But if you run supersets or circuits where the load changes constantly, the dial is a real, daily upgrade. The 5-in-1 does claw a little back with its included storage tray, which the Bowflex does not come with.
Build, brand, and the honest risk
The Bowflex is a known quantity from an established brand — a benchmark that thousands of home lifters rely on. The 5-in-1 is a generic listing, which means quality varies more and you should read current reviews before buying. That is not a reason to avoid it; it is a reason to buy it with clear eyes, as a cheap way to test the waters rather than a lifetime purchase. If you are weighing whether an adjustable pair is even the right call, our guide on whether adjustable dumbbells are worth it covers the trade-offs first.
Price and value
Prices move, so check the live figure on our best adjustable dumbbells page before buying. The stable truth is the relationship: the Bowflex costs roughly double the 5-in-1. For a committed beginner, that premium buys twice the ceiling, a faster dial, and a build you will not replace — so it is often cheaper over time than buying a starter set and upgrading later. For someone genuinely unsure, the 5-in-1 lets you answer the "will I even use this?" question for the least money, and you can move up to a Bowflex-class set once you know.
The upgrade path
Think a step ahead, because the two sets lead to different places. The 5-in-1 is designed as a proving-ground purchase: cheap enough to risk on an unproven habit, capped at 25 lb, and likely to be outgrown on your bigger lifts within a few months if you stick with training. When that happens, you move up — often to a 52.5 lb set like the Bowflex — so the 5-in-1 can end up being the first of two purchases. That is not a failure; it is the cost of finding out cheaply whether home lifting is for you before committing more money.
The Bowflex, by contrast, is built to skip that middle step. Its 52.5 lb ceiling lasts most beginners a year or more, and by the time you approach it you will know exactly whether to invest further — perhaps in an even heavier dial set. Buying the Bowflex first means one purchase that carries you a long way, which is why, for anyone reasonably confident they will train, it is usually the cheaper choice over time despite the higher sticker price. Weigh the 5-in-1's low entry cost against the real possibility of replacing it, and the Bowflex's higher price against the fact that you are unlikely to need anything else for a long while.
How to decide in 30 seconds
- Confident you'll keep training? Buy the Bowflex 552 — the buy-once default with room to grow.
- Rock-bottom budget, or unsure it'll stick? Buy the 5-in-1 as a cheap test, then upgrade later if the habit takes.
- Want the dial feel but worried about price? Compare the Bowflex against the other leading dial set in our Bowflex 552 vs. NÜOBELL guide.
For most people setting up a first home gym they intend to use, that lands on the Bowflex 552. The 5-in-1 is the right call only when budget or commitment is genuinely in question — and there is no shame in starting there. See where either fits inside a full costed gym in the $1,000 Build.
