General Thoughts on Adjustable Dumbbells: Versatile, Convenient, and Economical

General Thoughts on the Best Adjustable Dumbbell Set

The biggest benefit of adjustable dumbbells is their versatility. Once you buy a set and get the upfront cost over with, there is no maintenance cost or ongoing fees like a gym membership fee. As long as you don’t get too wild and crazy and drop the dumbbells on a hard floor or something like that, these dumbbell sets are built to last a very long time. Then it is really up to you to stay disciplined and stick to a workout regime. Furthermore, there are many lifts you can execute with dumbbells. Bench press, incline press, decline press, military (shoulder) press, bicep curls, tricep extensions, back rows are just a handful of examples. Whether you want to tone with high reps and low weight, or build mass with high weight and low reps, you can easily adjust the weight to your liking. Truly, it is possible to craft a holistic workout routine with a set of adjustable dumbbells and an adjustable bench.

Another great benefit is the convenience factor. Instead of working up the motivation to make the 10 or so minute drive down to the gym all you have to do is select your weight and pick up the dumbbells to get going, then let your momentum carry you the rest of the way through your workout. Even if you are just doing a set here and there between commercial breaks or what have you, it is still better than doing nothing. Sure, sporadic training isn’t the most optimal way to build muscle, but again something is better than nothing and you will build muscle slowly but surely.

Instead of buying 8-10 sets of single paired dumbbell weights, you simply buy an adjustable “block” of dumbbells. It is as straightforward as turning a knob or sliding a weight pin to select the exact weight you want. Not only will these cost you less, they also have a smaller footprint so they can fit in a corner of a room or small space in your garage. Unfortunately not all of us have enough space to have a roomy dedicated home gym area.

Adjustable Dumbbell Lifts and Exercises

One of the best things about using dumbbells for strength training is that they are free weights. Free weights are best for maximizing muscle development because it forces you to do all the work. Another study in the Strength and Conditioning Journal shows that free weights are superior versus machines. Unlike machine assisted exercises that keep the weight on a dedicated track, you have to use stabilizing and balancing muscles to help support the weight. This means each rep is working many more muscles than using a machine. Furthermore, dumbbells are also harder than barbell and other bar lifts with free weights because you can’t share the weight across both arms. Each arm has to do its own thing. This is why, for example, dumbbell press is much harder than traditional bench press. A person who can max 225 pounds on traditional press will likely only be able to  do about 180ish pounds with dumbbells.

Here are some of the top core dumbbell exercises:

  1. Dumbbell Press. Just like bench press, dumbbell press is an essential lift for building the chest and arm muscles.Dumbbell Bench Press
  2. Dumbbell Incline Press. This exercise is a variation of the dumbbell flat press, but instead you’re honing upper chest muscles.Incline Dumbbell Press
  3. Dumbbell Shoulder Press. This exercise is performed sitting down, ideally with some form of back support. It works the shoulder and upper chest muscles.
  4. Dumbbell Squats. Squats are a core lift of any workout regime. Combine dumbbell squats with lunges and you’re legs will be feeling in the next day.
  5. Dumbbell Curl. One of the most common dumbbell lifts is the curl. This isolates the bicep and gives it a thorough beating.Dumbbell Curl
  6. Dumbbell Tricep Kickback. Along with dumbbell press, the tricep kickback will help develop the largest arm muscle: the triceps.
  7. Dumbbell Kneeling One Arm Row. This is an effective back exercise that is much better than using a machine row.
  8. Dumbbell Lateral Raise. The lateral raise is a shoulder exercise that hits the side deltoid muscles. You can also combine this with front raises and shoulder press for a total shoulder workout.
  9. Dumbbell Upright Row. Another back exercise, this hits many of the muscles that the kneeling one arm row misses.
  10. Dumbbell Stationary Lunge. One of the most effective leg exercises with dumbbells is the lunge. You can either stay put or if you have room you can walk and alternate legs.
  11. Dumbbell Toe Raise. The toe raise is an excellent exercise for working out the calf muscles. has a great comprehensive list of dumbbell exercises if you’re looking for more.

Another idea is Virtual Trainer Dumbbell. It is an excellent smart phone app that will give you many ideas about how to use your new dumbbells. There are dozens of exercises featured in the app. It also shows you which muscle groups are targeted and how to perform each exercise.

Types of Adjustable Dumbbells

The main distinction between dumbbell products is whether they are best for strength training or conditioning workouts. Strength training aka pumping iron to build muscle mass obviously involves lifting heavy weight and doing a lower amount of sets. Bodybuilders or anyone interested in putting on some bulk will want to buy a set optimized for this use. The goal here is to keep increasing to heavier loads, and in turn your muscles will grow. With this style, it is best to take plenty of rest between sets, so swapping and making weight adjustments on the fly is not necessary.

Aerobic dumbbell sets are used for activities like CrossFit style or P90X workout videos. This incorporates the high rep many sets style of lifting. The main goal here is to increase cardiovascular health and overall endurance. You are looking to burn fat, sweat a lot, and “get in shape.” Typically there is very little time between sets (about 15-30 seconds). This is because you want to keep your heart rate up as sustain it for the duration of the workout.

Some experts recommend a training program that involves some of both styles. Most dumbbells are designed for one lifting style or the other, but a few excel in both categories.
