Does a Punching Bag Build Muscle? The Truth About Strength and Boxing

Boxing’s intensity makes for an ideal cardio workout. But does a punching bag build muscle?

Boxing drills definitely get the heart pumping while the bag resistance engages multiple muscle groups at once, building strength.

In this article, learn how boxing promotes muscle growth, transforming the body over time, as well as delivering other gains besides just strength.

Boxing vs. Weightlifting: Which Is Better for Building Muscle?

Typically, progressive overload leads to muscle growth. This includes gradually increasing resistance and/or weight repetitions in your exercises. 

Though a punching bag workout for muscle growth is effective, boxing training doesn’t target muscles in the same way as weightlifting. 

In weightlifting, this is achieved by gradually adding more weight and doing more repetitions. In boxing, the resistance of punching the heavy bag is what generates muscle growth over time. 

Both are effective though weightlifting works better if you want to bulk up. Whereas, the mix of cardio and strength training in boxing helps to develop lean muscle mass, making you quicker and stronger on the mat.

Leveraging Punching Bag Workouts for Endurance Training

Muscle growth actually occurs during rest periods when the body is in repair mode. Through protein synthesis, the body fuses microscopic tears in the muscle fiber and builds them back stronger.

First, though, to expand muscle size, there must be increased time for the muscles to be under tension. Standard weightlifting sets last between 30-45 seconds. Meanwhile, in a typical session, there are multiple heavy bag rounds, each of which lasts several minutes, often with cardio-focused exercises in between. 

This means boxers put their muscles under tension for longer periods to improve muscle growth. It also boosts endurance and maximizes cardiovascular output.

Can Boxing Replace Weightlifting for Muscle Gain?

If your goal is to bulk up, weightlifting is the better option. However, if you want to develop lean muscle, punching bag workouts are ideal to strengthen and tone the body while also building agility and speed.

The best way to boost muscle growth is to alternate between both. Most boxers switch up their daily routines and keep at least one day for rest to allow the muscles to repair. 

Here’s what a sample workout week may look like: 

• Monday and Wednesday: Focus solely on boxing techniques and form through speed bag training or shadowboxing 
• Tuesday and Thursday: Perform weightlifting circuits
• Friday and Sunday: Combine boxing training with weightlifting

Switch up your schedule to find a good rhythm that works for you and don’t forget to leave time for rest.

What Happens After Six Months of Heavy Bag Training?

Boxing training requires consistency to see results. If you partake in an hour-plus, heavy bag workout 4-5 times per week, you could expect: 

Month 1: Increased forearm strength and improved endurance 

Month 3: Lean muscle mass on the arms and legs, a stronger core, and more dynamic punching power

Month 6: Visible muscle development in the shoulder, back, and chest

After the six-month mark, as you continue training, you’ll see improvements in muscle growth and boxing performance, as well as better cardiovascular health, enhanced explosiveness and speed, and more muscle definition.

Keep in mind, these types of results are dependent on the intensity of workouts and nutritional habits. A well-balanced diet, packed with protein-friendly foods, is the optimal complement when you want to build strength.

FAQs About Punching Bag Workouts for Muscle Growth

Can You Get Ripped Just from Punching a Bag?

To get “ripped” to a point where the muscle definition pops, it takes more than just strength training. Diet is a crucial factor in achieving a chiseled look. 

The average boxing workout burns 400-700 calories per hour aiding in weight loss and lean muscle mass. However, to contribute to muscle definition, eat lean proteins and nutrient-dense foods while cutting out sugar, gluten, and alcohol.

Even if you’re not ripped (which takes a significant amount of discipline, it doesn’t mean you aren’t gaining impressive strength. It all depends on what your goals are and how your body reacts to training and dietary habits.

How Often Should You Hit the Punching Bag?

In the beginning, aim for hitting the bag at least two to three times a week to steadily build muscle growth. As your strength and endurance increases, you can work up to four to five days per week to maintain momentum. 

Most importantly, listen to your body. Depending on whether boxing is your only workout or if you incorporate weight training and other exercises, make sure you have plenty of recovery time to prevent injury from overusing the muscles.

What’s the Best Punching Bag for Muscle Growth?

Heavy bags, weighing anywhere from 70-100+ lbs. provide the most resistance to champion muscle growth. However, quicker, repetitive punches on a double-end bag or freestanding bag can be just as beneficial.

You can get in a punching bag workout at the gym or at home with the right gear and equipment, including a heavy bag, boxing gloves, and hand wraps.
