ST1 Tether System
Built for water fitness — not lap swimming. The ST1's rigid, low-profile pole gives you a fixed anchor point for aerobics, resistance training, and aquatic therapy.
Why the ST1
Steady & Stable
Only 7 inches of flex means the pole barely moves — and that's the point. For water aerobics and resistance exercises, you want a fixed anchor, not a flexible one. The ST1 holds you in position.
Low Profile, Easy Storage
At just 24 inches tall, the ST1 sits below most pool fences and is barely visible from the deck. One-piece construction — drop it in the base, pull it out when done. Nothing to assemble.
Built for Water Fitness
Water aerobics instructors, physical therapists, and swim spa owners choose the ST1 because the rigid anchor point lets you train without the pole absorbing your effort.
Your Anchor in the Water
The ST1's single 0.75-inch fiberglass rod is intentionally rigid. 7 inches of flex is enough to feel natural but firm enough to keep you locked in position during resistance band exercises, aqua jogging, and rehab movements.
If your goal is fitness rather than freestyle — this is your model. The pole holds its ground so you can focus on your workout instead of fighting the equipment.
Swim Spa Ready
The ST1's compact 24-inch height is ideal for swim spas, where taller poles can interfere with covers and shells. Pair it with the factory-installed base your spa likely already has, and you're training in minutes.
Combine with the Row Kit hardware for a complete swim spa workout station — swimming, rowing, and resistance training from a single mount point.
What's In the Box
Every ST1 system ships complete: single-piece fiberglass pole, your choice of base, Dynamic Stretch Cord with carabiner, swim belt, and nylon carry bag.
Free shipping on orders over $99 in the continental US. International flat-rate shipping available.
