Top-load adjustable farmer's walk handles have long been my preferred choice for most training environments; top-loading makes it far easier to adjust between increment changes and also means that you haven't got to worry about locking collars - the weights aren't going anywhere. As you'd expect from ATX, this pair of farmer's walk handles are seriously heavy-duty.
Handles sold as a pair.
Suitable for use with olympic (2"/ 50mm) weight plates. Sold separately.
