Mega Curl

This machine, like many of our other launches came from inspiration and imagination in the gym. Two things we have not seen in a typical/traditional preacher curl machine is an adjustable width and/or THREE (3) different grip options. Our Mega Curl has supinated, pronated, and neutral grip options, just by a pull of a pop pin. You can also now adjust the width of the supinated and neutral grip! This allows you to focus more on the long/outer and short/inner heads of your biceps! There are four (4) different width options for these two (2) grips. For the pronated and neutral grips, each handle is flipped from the right arm to the left and vise versa. For the pronated grip, be sure to have each handle on the furthest hole on each arm to keep the handles from hitting. (See photos, videos, and demonstrations for examples.) Having all of these adjustments and grip options makes this machine speak for itself. This machine also only requires a small footprint of approximately 3’ x 4’ (W x L).

Best GHD for a Home Gym — July 2026

What is a Machine?

What a strength machine is

A strength machine guides the resistance along a fixed path so you can train a movement safely, often without a spotter. The main types: selectorized (pick weight with a pin), plate-loaded (add your own plates for a heavier ceiling and better feel), and functional trainers / cable machines (adjustable pulleys for dozens of exercises).

Machines vs. free weights

Machines shine for isolation, safety, and high-rep hypertrophy, and for training hard alone. Free weights build more stabilizer strength and carry over better to sport. Most well-rounded home gyms use a rack and barbell as the core and add one machine — often a cable/functional trainer or a lat-pulldown/row — to fill the gaps.

The sub-types worth knowing

“Machines” covers several categories that barely compete with each other: GHDs for hamstring and posterior-chain work, belt squats for loading the legs without the bar on your back, leg press / hack squat combos for heavy quad volume, reverse hypers for posterior-chain work and lower-back decompression, cable towers and functional trainers for pulling movements, and row machines. Pick the one that fills a gap in what your rack and barbell already do. Almost nobody needs two.

Space and standalone vs. rack-mounted

Most of these come in a standalone version and a cheaper rack-attachment version. The attachment saves floor space and money, but often gives up stability or range of motion — a tradeoff worth checking on the specific product rather than assuming, since it varies a lot between designs.

A note on ratings

Machine listings frequently show a manufacturer’s own on-site rating, which runs high (4.7–5.0 is typical) and sometimes pools reviews across a whole product family rather than the exact configuration you’re buying. Where we have independent hands-on coverage, our summaries anchor to that instead, and say so on the product page.
