J-Bands Jr. — Lighter tension designed for ages 12 & younger

J-Bands are an integral part of our Arm Care Program and a prerequisite to our Throwing Program. The eleven step J-Band exercise routine is designed to balance, strengthen & condition the rotator cuff & surrounding muscle groups. The J-Band exercise routine is crucial for injury prevention, endurance, recovery period and increased velocity. It is an essential workout for any player whose goal is to have a long and healthy career.

The J-Bands allow you to perform 11 basic exercises to strengthen and protect the rotator cuff muscle group.

Workout Reminders 

1.  Exercises are to be done PRIOR to throwing (or on average of 3-5 days a week during periods of time off)

2.  One set of 25 repetitions per exercise (Exercises 2 & 3 involve using the breath while stretching in 30 second increments) 

3.  Quality over Quantity

4.  Maintain proper technique, alignment, etc

5.  Keep pace fluid in both directions

6.  Keep arm, body, and mind relaxed

7.  Keep long, fluid breathing patterns

8.  Walk closer to the fence to reduce tension

9.   Work to the point of fatigue rather than failure.


Important Notice and J-Band™ Care information 

BE SURE that the silver clip is NEVER in alignment with your face or head. The J-Band™ is not a toy and should not be used in any way other than the exercises that it is designed for. The J-Band™ is NOT to be stretched more than one-to-two feet of its original length — even for the strongest of students. Increase reps if needed.

Keeping it out of the sun and away from your cleats (when not in use) will help maximize the longevity and safety of your J-Band™.



The exercises are designed to target the delicate rotator cuff muscles that do not need huge amounts of tension. The bigger muscles of the body take over if there is too much tension in the band during the workout. If you are working with the band at twice it’s original length and feel like you need more of a workout, it is recommended that you increase your repetitions rather than the tension of the J-Band. For example, increasing your repetitions from 25 to 35 reps on each exercise will make a huge difference in the workout even for the strongest of students. It will also ensure that the rotator cuff muscle group stays very active.

To maximize the life of the J-Band, store it in a safe place after the workout. Keeping it out of the sun and away from your cleats (when not in use) will help maximize the longevity and safety of the J-Band.

Thank you very much for your order and please do not hesitate to contact us with any questions you may have. Sincerely, Jaeger Sports Inc.
