Simple Indian Club Exercises ebook by Staff Sergeant Alfred Moss. This ebook describes
many exercises that can be performed using Indian Clubs, which consists of swinging weighted clubs in different and sometimes elaborate movements in order to strengthen and increase mobility in your upper body.
Benefits of Indian Club training include: 
Shoulder strength and flexibility. This is perhaps the biggest benefit of Indian club training. As you know, your shoulder sits in a socket and has a wide range of motion. Unfortunately, most strength training exercises that target the shoulders, like the shoulder press, employ a very limited range of movement. Indian club training ensures you work your shoulders using their full range of motion, thus providing more complete shoulder strength and flexibility. If you’re involved in any sport that requires strong, flexible shoulders (and elbows too) like baseball, martial arts, and tennis, you’ll definitely benefit from Indian club training.
Grip and forearm strength. I was surprised how quickly my forearms began to burn when I first started swinging clubs. Holding a weight that’s at the end of a handle requires ample forearm strength. Also, holding onto the clubs so they don’t go flying out of your hands mid-swing helps you build a grip like a vise.
Core strength. The swinging motion requires you to engage your core muscles in order to stabilize your trunk.
Body coordination. Some of the more advanced Indian club swings require highly developed body coordination skills. I feel like a complete spaz doing some of them and have knocked myself in the brain canister a few times as I’ve learned new movements. But I’ve gotten better with practice. In fact, the body coordination benefits were a big reason why the U.S. Army had soldiers train with Indian clubs. According to the 1914 U.S. Army Manual of Physical Training: “The effect of these exercises, when performed with light clubs, is chiefly a neural one, hence they are primary factors in the development of grace and coordination and rhythm.” So not only are you working your shoulder muscles, you’re working the old noodle, too.
Cardiovascular exercise. Once you have a set of moves mastered, you can create a non-stop routine where you transition from exercise to exercise quickly. All that arm flailing can really get your heart going.
Great for rehab and prehab. If you’re nursing an injured shoulder or other upper body muscle, performing slow and controlled Indian club exercises are a great way to rehab. And many therapists recommend Indian club training as a way to “prehab” or prevent injuries from happening in the first place.
It’s fun! I like training with Indian clubs because it’s really quite fun. The challenge of mastering the various swings serves as motivation to keep working with the clubs. I always feel great when I finally get the hang of a new movement.
 
Staff Sgt Alfred Moss (1868-1952) was a prominent bodybuilder, strongman and gymnast, who was a well known figure in the British Army during the late 19th century. He primarily served in the 8th King's Royal Irish Hussars regiment, and went on to win the British Army Gymnastics Competition in 1900. Following his time in the military, Moss went on to work as a physical instructor, a career which he continued into his late 60s. Notably, he was a highly regarded competitor at Bernarr Macfadden’s 1903 Perfectly Developed Man Competition, and made it through the contest’s opening rounds. However, he was later disqualified for having tattoos. Moss later published several books on physical culture, including Pyramids for Gymnastic Display (1935).
