The Benefits of StairMaster TwistLock Weights

Super Easy to Adjust

stairmaster twistlock adjustable dumbbellsAs the name implies, all it takes is a simple twist of the handle to change weight.  These compare to the simplicity of the Bowflex SelectTech series.  Just twist to display the desired weight in the window on the handle and pull from the mount.

Each weight adjusts from 5 to 50 lbs in 5-pound increments, making them a great choice for women or those not looking to bulk up too much.

Look and Feel of Traditional Dumbbells

StairMaster engineers and designers wanted to make their adjustable dumbbells to mimic the shape and feel of gym quality, commercial style dumbbells. Unlike other sets who may have a bulkier shape and feel, Stairmaster wanted the TwistLock dumbbell system to feel more familiar to the end user.

More Compact Design

While the length of these dumbbells is only slightly shorter than the Bowflex SelectTech 552s at the full 50-lbs, the length fluctuates depending on the weight size.  Whereas the 552 are always 15.75″ long regardless of weight, the TwistLocks length varies greatly from the 5-lb to the 50-lb selection.

Great for Supersets

The StairMaster TwistLocks are probably the best option in adjustable weights if you’re looking to do supersets.  The combination of their compact design and super fast adjustment make these the top choice for quickly transitioning between weights.

Drawbacks of the StairMaster TwistLock Adjustable Dumbbells

Not as Durable as Some Other Sets

Unlike the Yes4All or traditional dumbbell sets, these weights have some plastic parts and need to be treated more carefully.  You cannot drop them.  It is wise to have them always in the cradle when not in use to protect them from undue stress.

Sticks in Cradle at 50lbs

Some users have complained that the weights may adhere to the cradle when you are choosing the 50-lb option. This could be quite an irritant if you’re having to use both hands to pick up one weight.

No Expansion Pack

At this time, these weights have topped out at 50-lbs each so there is no room to grow.

Very Pricey

These weights are one of the highest priced options on the market considering they peak at 50-lbs.  The price is more in line with the PowerBlock Elite 5-90 lb Set.  Add in the cost of the stand (not included) and you’ll be paying twice as much as the comparable Bowflex SelectTech 552s.

Were it not for the price, these would be one of our top choices in the adjustable dumbbell market. The ease of adjustability coupled with the feel of traditional dumbbells put these way out front in performance and style. And with the well-respected brand of StairMaster behind them,  these should be given serious consideration. But, while we love these weights, we are struggling with the price point. Having said that, if the cost is not an issue and you don’t see yourself needing to exceed 50 lbs of weight, these would make a great addition to your home gym.
