Arm exercises strengthen and tone your muscles and generally have a positive impact on your health. A study published in 2018 found robust lower arm and "grip strength" reduced the risk of heart and respiratory diseases, as well as some types of cancer.1
This 30-day challenge includes arm workouts that will help strengthen your biceps, triceps, and forearm muscles while boosting your muscular endurance. It also involves core and cardio work.

Arm Muscles
Each of your arms consists of 24 muscles, which help move and flex your arms. Key muscle groups that you work while exercising your upper body include:23Biceps: This is the large muscle in the anterior (toward the front of your body) compartment of your upper arm. Your biceps have two heads: a short head and a long head. This muscle helps move and flex your elbow and forearm.
Forearm extensors: These muscles are located in the posterior (toward the back of your body) compartment of your forearm. Extensor muscles help extend your wrist and fingers.
Forearm flexors: These muscles are located in the anterior compartment of your forearm. Flexor muscles help bend your wrist and fingers.
Triceps: This is the large muscle in the posterior compartment of your upper arm. The triceps have three heads and help extend and flex your elbow and shoulder.
Tips
This 30-day arm workout challenge involves doing three sets of each exercise and 10–15 reps of each exercise per set. You'll work your biceps and forearm muscles with curls and target your triceps with dips. Other exercises like planks and weighted shadowboxing work your core muscles and get your heart pumping.
You'll build up to doing more exercises. You'll only do the exercises from day one on that day, for example, and then the exercises from day one and two on day two. You'll do the exercises from days one to three on day three and so on.
This schedule also includes one day of rest every five days. Rest days allow your muscles to regenerate and help you avoid injuries. You would do the exercises from days one to four and six on day seven, for example, with a rest day on day six.
Start with weights that make it difficult to complete the final couple of reps. You are at the right level if you feel some fatigue by the end of the exercise. If you are new to these exercises, you'll want to use lighter weights, about one or two pounds. You can try challenging yourself with heavier weights as your strength increases. Build up to three or five pounds or more if you feel comfortable.
