This was written during the pandemic but swim tethers are still popular with swimmers with a small backyard pool and for swimmers and triathletes who want the keep swim training when on holiday and on business travels. These tethers can be used in small hotel pools or small pools in holiday villas.
With local pools shut and no access to the open water you might think you have no swimming options beyond splashing about in your bath. But a garden pool is not as expensive as you might think and will allow you to train using a swim belt, bungee or tether. It’s very effective and actually a great workout. See below for some pool options available online for delivery.
Training with a swim belt or tether can increase speed, improve technique and endurance for an overall stronger open water swim. Whether it is practising bilateral breathing, kicking or sighting, a swim belt/tether should be part of your swim training.

So, what is a swim tether?
There are two common types of tether, a swim belt waist tether or foot tether. A swim belt is a strap that fits around your waist and has an elastic cord attached to a plastic ring at the back. The belt can easily be attached around your waist by an adjustable clip component at each end. Another form of tether is one that attaches to your feet via booties or ankle straps.
I have tried both types and I personally prefer the ones that tether to your feet. They give you great feedback from your feet and whether your legs are splitting during your stroke and causing extra drag. You can also get a sense of your body rotation. Tethered swimming is great to really tune in to what your entire body is doing.
The tethers that goes around your waist are also great for all swimming strokes so, if you can, try both. However, the belt types of tether may need attaching higher up to avoid impeding your feet and aiding rotation.
I use a Swimovate Poolmate watch to record my swims when using a tether as other watches may only use GPS – during tethered swimming your GPS watch won’t show good data as you won’t be swimming very far!
You simply attached your swim tether around your waist or feet/ankles and the other end to a pole or fence post and get in the pool and swim away from the where you have tied the other end to. You swim stationary in the pool.
Note that as you are stationary you are not creating a bow wave and pocket or air to breath into so you may need to turn your head slightly more.

The Advantages of Tethered Swimming
There are many reasons to choose a swim tether to aid with your swim training and here are a few reasons to consider purchasing this cost effective piece of swimming kit.
Swim belt training can:
- Be used for a variety of sessions including technique, strength and endurance.
- Improve your ability to swim in a straight line instead of weaving from one side to the other.
- Aid in practising bilateral breathing, helping you concentrate on the least amount of head rotation you need to take a breath on each side.
- Improve your kicking by allowing you to concentrate on the motion from your hips and thighs rather than from your knees.
- Enable you to work on sighting, which is something all open water swimmers need to practise. Set up a water bottle or cone on the other side of the pool as something to sight on. Lift your head slightly with your eyes just above the water like “crocodile eyes” and then breath to the side. Try not to breath to the front as your hips will sink low and cause drag.
- Be a good tool for drills, especially one-arm drills. Swim with one arm for a set amount of time, then switch to the other. This drill will help produce a more even stroke. You can also use it with other kit such as paddles and a swim snorkel.
- Help to minimise over-rotation by letting you concentrate on equal rotation for each side.
- Allow you to apply the same pull force with each arm and aid in a full stroke for each arm.
- You can also use your swim tether for water running. Water running is a great way to run with low impact. Ideal for re-hab.
Swim tethers are also ideal for taking on holiday of business travel where you hotel may have a small or odd shaped pool where lengths are not possible.
Training Session Example
When tethered swimming you are stationary so you can't swim to speed or distance so I wrote this session based on time swimming and number of strokes taken. This example swim session can help you create your own tethered swim session. If you would like more tethered swim sessions you can find them in my free swimming book.

FAQ: Tethered Swimming in a Small Pool
Q1: What is tethered swimming?
Tethered swimming is a form of stationary swimming where a swimmer remains in one place while swimming against a resistance provided by a tether or cord attached to the swimmer and anchored to a fixed point.
Q2: Can I practice tethered swimming in a small pool?
Yes, it's possible to practice tethered swimming in a small pool. However, it's important to ensure that the pool is deep enough for the swimmer to comfortably swim without touching the bottom. You can use a hotel pool when on holiday or on business travel or a small pool in a holiday villa.
Q3: What equipment do I need for tethered swimming?
You'll need a swim tether system, which typically includes a harness or belt for the swimmer, a cord, and an anchor point. Additionally, you may want fins, a snorkel, and a swim bungee for added resistance and support.

FAQ: Designing a Tethered Swimming Session
Q1: How do I begin designing a tethered swimming session?
Start by identifying your goals. Are you aiming to improve endurance, work on stroke technique, or focus on strength training? Tailor your session accordingly.
Q2: What are some key components of a well-rounded tethered swimming session?
A balanced session typically includes a warm-up, main set, and cooldown. The warm-up prepares your body for the workout, the main set is where you focus on specific goals, and the cooldown helps your body recover.
Q3: How long should a typical tethered swimming session last?
The duration can vary depending on your fitness level and goals. Beginners might start with 20-30 minutes, while more experienced swimmers can extend sessions to 45-60 minutes. Always listen to your body and adjust accordingly.
Q4: What should I include in the warm-up for a tethered swimming session?
Begin with light, dynamic movements to get your heart rate up. Incorporate arm swings, leg swings, and gentle strokes to activate the muscles you'll be using in the main set.
Q5: How can I structure the main set for a tethered swimming session?
The main set should align with your goals. For endurance, focus on longer intervals with short rests. For technique, include drills and focus on form. Strength training may involve intervals with added resistance or using equipment like fins and paddles.
Q6: Can you provide an example of a tethered swimming session for strength training?
Sure! Here's an example:
Warm-up (10 minutes): Light flutter kicks, arm circles, and freestyle strokes.
