Dumbbells a workout necessity
Anymore, Dumbbell weight sets are a necessity in any home gym. If you’ve been pounding away for years on a bike or treadmill doing your cardio exercises – faithfully – but your fitness level has reached a plateau, what can you do? The answer lies in varying your workout by exercising with free weights, i.e., dumb bells and barbells.
Use Free weights to advance your training

Most fitness trainers will tell you that dumbbell exercises are a must in weight lifting. To get an idea of what they can do for you, imagine how muscles work together when opposing each other.
On any given lift, one muscle is contracting and another is relaxing, such as the biceps and triceps when performing a biceps curl with a dumbbell in each hand. Since the tricep must be move as well, the bicep is not completely isolated. Hence, doing multiple sets of repetitive exercises using dumbbells will work the target muscle — but it goes a step further.
Pick up a 10-lb dumbbell in each hand and do a set of ten reps. Immediately, you notice you’ve changed the dynamics of the workout by adding 20 lbs or more to your body weight. Now larger stabilizer muscles in your abs, legs, and back have to work to keep you in balance. By using free weights you’re actually developing your large stabilizer muscles (not to mention your coordination!) and this compound movement results in the most effective gains for muscle growth.
Reach Your Goals Faster

It’s important to do sets of dumbbell lifts in your weight training because they provide an advantage to toning your muscles – even if you train only two or three days per week for 20 minutes each visit.
The aim of weight lifting is to increase strength, but did you know it also creates a burn rate of 250 to 400 calories an hour?
Any improvement in your lean muscle mass and metabolism will help you to increase fat burn at all times (even while sleeping). This is something cardio alone can’t achieve. You need to add weight training to burn optimum calories.
Toning your muscles using dumbbells is essential if you want to achieve an ideal weight on your frame since a pound of muscle requires about 30 to 50 calories per day just to support itself, while fat cells don’t burn up a thing. So pick up a set of dumbbells, start pumping, and get off that plateau.
