The Keiser Air 250 Leg Curl is a seated air resistance leg curl machine designed for specific hamstring work. Its resistance is adjustable from 1 to 118 kg, offering an alternative that is just as effective as free or guided weights, while limiting stress on knee joints and adjacent connective tissue. In fact, the resistance applied during the initial and final phases of the effort has been deliberately reduced to avoid any risk of injury.

The Keiser Air 300 Leg Curl Pro is an elongated air-resistance leg-curl machine designed for specific hamstring work. Its resistance is adjustable from 3 to 111 kg, offering an alternative that is just as effective as free or guided weights, while limiting stress on knee joints and adjacent connective tissue. In fact, the resistance applied during the initial and final phases of the effort has been deliberately reduced to avoid any risk of injury.

The Keiser Air 300 Squat is a guided air resistance machine that was developed for explosive posterior chain work. Thanks to its variable resistance (limited resistance on the phases that are hard on the knee), which is fully adjustable from 18 to 318 kg, it is an ideal machine for those looking for performance. Its integrated display also allows real-time monitoring of effort during the work phase.

The Keiser Air 300 Squat Pro is an improved version of the standard Air 300 with an intuitive wedge system for easier starting and stopping of the movement.

The Keiser Single Pulley is an innovative device combining the versatility of an adjustable pulley tower with a real-time performance display system (tracking resistance, number of reps, etc.). Its pneumatic resistance is adjustable from 1 to 34 kg to adapt stress to the exercise carried out.

Compatible with the Infinity Accessory Kit.

The Keiser M3i Total Body Trainer is a pro cardio trainer based on the structure of the M3i bike. The difference is the front swing arms that replace the standard handlebars to allow for full body work. The pedals and swing arms are connected to each other allowing for passive resistance exercise.

The Keiser Functional Trainer is a pneumatic resistance machine designed for use in return-to-sport training or physical preparation. It is a versatile system with two pulley stacks allowing several athletes to work simultaneously with various angles and resistances. The progressive resistance is adjustable from 1 to 22 kg per arm, and its central display panel is perfect for tracking athletes' performance in real time.

Compatible with the Infinity accessory kit.

The Single Platform Option for Keiser Functional Trainer is an accessory that allows the Functional Trainer to be attached directly to the floor. The platform acts as an interface between the bottom of the machine and the floor, and it must be screwed directly to the floor to guarantee the balance of the Functional Trainer.

The Keiser Functional Trainer Free Platform Option is an accessory designed to support the machine without the need to screw it to the floor. Its design effectively stabilises the Functional Trainer while limiting the amount of space required to integrate it into your training area.
