The Stand Up Str8 Junior is a smaller version of our standard Middle Back Strengthener—designed specifically for children (ages 8–15) and petite adults with a shoulder width of 39 inches or less.
Just like the original, this patented device features two cushioned arm loops connected by a durable elastic resistance band that targets the key muscles responsible for healthy posture and upper-back support.
Using the Stand Up Str8 Jr. for just two minutes a day, three times a week helps:
Reverse poor posture developed from phones, gaming, or prolonged sitting
Relieve strain and tension in the neck, shoulders, and upper back
Build lasting postural strength in the middle back—the foundation for lifelong alignment
Comfortable, effective, and easy to use, the Junior version offers the same proven benefits in a size tailored for smaller frames.
