What is the Jacobs Ladder X?

Jacobs Ladder X - JLX

Designed with multi-functionality in mind, the Jacobs Ladder X is a revolutionary piece of fitness equipment that takes the old Jacobs Ladder climbing machine design found in the jacobs ladder, and jacobs ladder 2, but adds new and improved features and benefits. 

We compare all three machines in our resource, the jacobs ladder vs jacobs ladder 2 and compare each ones pros and cons to help decided which is best for you.

The JLX's unique design features an angled ladder-like structure with rungs that mimic climbing stairs, allowing for a full-body workout that engages muscles you didn't even know existed. But it's different from its relatives.

The Jacobs Ladder X is a 3 in 1 ladder climbing, stair stepping, sled driving, cardio machine. It brings all the other Jacobs Ladder machine benefits, with new and improved features.

But what sets the Jacobs Ladder X apart from other cardio machines?

For starters, it's low-impact and easy on your joints while still providing an intense workout.

It also has dynamically adjustable resistance levels to accommodate users of all fitness levels and can be used for both high-intensity interval training (HIIT) or steady-state cardio sessions.

When compared to traditional stair machines and other workouts, the Jacobs Ladder X offers a more challenging and effective workout in less time – making it perfect for busy fitness enthusiasts looking to get the most out of their gym time.

Jacobs Ladder X Has 4 Distinct Positions

One of the unique features of the Jacobs Ladder X is its ability to be used in four distinct workout positions. This allows for a variety of exercises, muscle engagement, and an overall versatile workout. Let's take a closer look at each position and what it has to offer.

Side Rail Workout

The side rail position is a unique variation of the hand over hand climb. Instead of using your hands to climb the ladder, you plant them on the side rails and use your legs to do all the work.

This exercise targets your lower body muscles, particularly your glutes and hamstrings, while also engaging your core for stability.

The side rail position is a great option for individuals who want to focus on their lower body or for those who may have wrist or hand injuries that prevent them from doing the traditional hand over hand climb.

Plus, the added stability from the side rails makes it easier for beginners to maintain proper form and technique.

The Standard Hand Over Hand Climb

The standard hand over hand climb is the classic exercise most commonly performed with any of the Jacobs Ladder machines.

By mimicking the motion of climbing a ladder, this exercise engages your upper body, core, and lower body muscles simultaneously.

The ladder rungs are set at a 45-degree angle, which means you're climbing a steep incline, making it a more challenging exercise than just climbing a regular ladder or step machine.

The motion of this exercise is smooth, thanks to the self-paced ladder that adjusts to your speed, making it easy for beginners to jump right in.

Stair Stepping Position

The Jacobs Ladder X also has a stair stepping position. This a favorite JLX position of ours.

This position mimics the motion of climbing up stairs, providing a low-impact workout that is gentle on your joints.

This position is perfect for those who are recovering from an injury or have joint issues. It also targets your glutes, hamstrings, and quads, making it a great lower body workout.

Sled Driving Position

The sled driving position is a unique feature of the Jacobs Ladder X. In this position, you push and pull the sled across the machine, engaging your upper body, core, and lower body muscles.

This position is perfect for those who want to add some variety to their workout routine and target different muscles than the traditional ladder climb.

Plus, it's a fun and challenging exercise that will leave you feeling accomplished.

Overall, the Jacobs Ladder X is a versatile and effective cardio machine that provides a full-body workout in less time than traditional machines.

Its low-impact design and dynamically adjustable resistance levels make it suitable for users of all fitness levels. Plus, with its four distinct positions, you
