Can You Get Big Arms With 8-Pound Dumbbells?

Lifting weights can slow age-related muscle loss, increase your bone density, boost the number of calories you burn and help you sleep better. With the proper approach, weightlifting can also increase the size and strength of your muscles. Depending on the exercises you are doing and your current fitness level, 8-pound dumbbells may be the appropriate weight selection for you to get bigger arms, or you may need a different weight selection. When you do a variety of weightlifting exercises, use proper form with dumbbells that offer sufficient resistance and recover after your workouts, you can get bigger arms in a matter of weeks.

  1. Appropriate Weight

    • To build muscle, you need to use dumbbells that offer weighted resistance substantial enough to fatigue your muscles. You should feel muscle fatigue begin to set in after eight to 12 repetitions of a particular exercise. Depending on your current size and fitness level and the exercise you are doing, 8 pounds may be enough weight to effectively fatigue your muscles. When you train your muscles consistently, you will get stronger and be able to lift heavier dumbbells. The heavier the weight you can lift, the larger your muscles can potentially get.

    Proper Form

    • Though lifting heavier weights can help you realize more muscle mass, lifting them with poor form can hinder your performance, cause injury and target unintended muscle groups. Whether it is 8-pound dumbbells or 80-pound dumbbells, make sure the weight feels heavy enough to challenge your muscles without compromising your form. When you are doing biceps curls, hammer curls, triceps extensions, kickbacks or any other exercise to build strength and mass in your arms, use two counts to lift the weight with control and three counts to slowly lower the weight. Maintain a strong core and avoid swinging the weights.

    Add Variety

    • It is possible that 8-pound dumbbells may be heavy enough to fatigue your arm muscles during some exercises and too light to present adequate resistance for others. Continue to add variety to your arm workout so that your muscles stay surprised and have to work to acclimate to any given weight. Vary the exercises you do and the order in which you do them. When you introduce your muscles to new exercises, you may need to use lighter dumbbells than what you typically use until you get stronger.

    Refuel and Rest

    • Muscles grow during rest. Allow yourself to recover from your arm workouts by resting 48 hours before you train the same muscle group again. Muscles also need protein to rebuild muscle fibers after you train. While eating protein-rich food and getting plenty of rest after your workouts will both help you build stronger, bigger muscles, you want to keep realistic goals. Gender and heredity play important roles in determining how big your muscles can get. Women do not have the testosterone that allows them to bulk up like men, and everyone's genes provide a general road map of muscle-size potential.
