Bottom Line

Assemble in mere minutes for a great way to build muscle without overtaxing your body.

Pros

Ideal for those who want to build and maintain muscle, but not max-out at weight levels suited for a gym environment. Used by men and women, with positive remarks in terms of quality and affordability. We love they fit easily beneath a bed.

Cons

Customers note the o-rings may fall off, however the set does come with spares.

Bottom Line

An ideal addition to your workout, especially for those on the move and also on a budget.

Pros

Customers appreciate the set is designed to minimize noise, making them ideal for at-home workouts. Ideal for those dedicated to daily workouts and in need of equipment that can stand the test of time and usage. A perfect set for those new to weight training.

Cons

It would be in your best interest to invest in a pair of weight gloves, as the handles can be rough to the touch.

Lift up to 105 lbs. at a time with barbells that include tight-fitting caps for secure and confident use.

Pros

In just 2 weights, customize your strength training workout anywhere from 2.5 lbs. to over 50 lbs. per side. Customers appreciate the durability of this cast iron set versus trendier systems made of cheaper material. Adaptable for multiple people with varying training objectives.

Cons

Be careful as the black paint from the plates may rub off.

Bottom Line

Not your typical cast iron option, but made of dense material that can fast forward your workout.

Pros

A perfect addition that can amp up your cardio routine or help you regain strength in joints and other areas. One of the lighter cast iron options available, this set is great for those who walk on a regular basis. Coated dumbells protect floors from dings and scuffs.

Cons

Reviews suggest there is an odor to the set that may distract from your workout.

Bottom Line

A cast iron classic that fits most budgets and workout agendas.

Pros

At 12 lbs. a piece, this set is designed for a total body workout that can tone major muscle groups in addition to isolated moves. In a good sense, these weights will work as expected. We love you can use these whether in your home gym or in front of the TV.

Cons

While fully capable of a complete workout, this set is limited to either 12 or 24 lbs. of weight to workout with.

Cast iron dumbbell sets can deliver a high level of workouts at home. Some of these barbells are molded, meaning you cannot add or remove weight. Others have plates that you can add to the bar to change the level of workout you’re doing. These sets will be sold in matching pairs. Weights in these dumbbells can range from 1 to 60 lbs. Cast iron dumbbell sets are available in a couple of different shapes too. The end of molded dumbbells may be round or in a hexagon shape. Some people prefer the hexagon shape because the dumbbells won’t roll across the floor. If you’re looking to save a bit of money, cast iron dumbbell sets are cheaper than rubber dumbbells.
