Cardio: the Sidea selection
The tag cardio Sidea features the machines from the HIIT LINE range — Air Bike, Air Row, Air Ski and Curve Run — all share a specific design principle: pneumatic resistance without an electric motor, which automatically adjusts to the power output of the athlete. No levels to set, no predefined upper limit. The intensity is determined by the person cycling, rowing or pushing. This feature makes them suitable for both competitive athletes and those embarking on a structured fitness programme, without having to change machines as their ability improves.
For those who do cardio
These machines have a wide range of applications, but they are not one-size-fits-all. Each tool is designed to meet specific requirements in terms of context and method.
Fitness trainers and sports coaches incorporate them into conditioning blocks as part of their weekly programme: 4–6 rounds of Assault Bike or Air Ski at maximum intensity have a direct impact on lactate-anaerobic capacity and VO₂max, as documented in the literature on high-intensity interval training. For team sports, endurance sports and martial arts, they provide a means of energy training that can be systematically incorporated into training programmes.
CrossFit box and functional training center Pneumatic machines are a well-established choice for WODs, AMRAPs and cardio benchmarks. The Curve Run, in particular, is popular for its non-motorised acceleration curve, which engages the hamstrings differently to a traditional treadmill.
Personal trainers in gyms make the most of the compact design of the machines to incorporate cardiovascular training into small spaces. The Air Ski, for example, is less than 1.5 metres long and can be secured to the floor using the dedicated floor stand.
Finally, anyone setting up a home gym If you’re looking for professional-grade equipment, this range offers a long-term investment: steel frames, chain or belt drives, frames without componentelectronic devices subject to obsolescence.
How to choose
The choice between the four machines depends mainly on three factors: the movement patterns you wish to prioritise, the space available and integration with other work tools.
Air Bike (HC002 / HC002V): coordinated cyclical movement of the arms and legs. It engages the glutes, quadriceps, hamstrings, back muscles and chest muscles simultaneously. Ideal for Tabata training, aerobic capacity tests (e.g. 10-calorie maximum sprint) and active recovery at a low cadence.
Air Row (HC003 / HC003V): simulates the rowing motion. It strongly engages the posterior chain — spinal erectors, latissimus dorsi, trapezius — with a push-pull pattern that complements strength programmes based on squats and deadlifts. It requires good hip and shoulder mobility to be performed correctly.
Air Ski (HC004 / HC004V): double-poling movement, identical to the Nordic skiing technique. Upper body only. Useful for isolating cardiovascular training without placing strain on the lower limbs — particularly relevant in cases of lower limb injuries or as a supplementary station in mixed circuits. The floor stand (HC004/2 / HC004/2V) is required for use on the floor.
Curve Run (HC001 / HC001V): free-running curved treadmill. Speed depends entirely on the runner: to accelerate, you need to lean your upper body further forward; to slow down, you need to reduce the force of your push-off. This mechanism increases the energy expenditure compared to motorised treadmills and promotes a running pattern that engages the hip flexors and calf muscles more effectively.
For those who need to fit out a space on a set budget and want to maximise the variety of exercises, the Air Bike + Air Ski combination covers the upper body and the whole body whilst taking up minimal space. Adding the Curve Run introduces a non-motorised running pattern.
Sidea cardio products
The range is available in two versions: the standard series (HC001–HC004) in the category HIIT cardio machines, suitable for professional gyms, boxing clubs and studios subject to intensive daily use; the V series (HC001V–HC004V), available in the section Outlet e Promotion Items, which gives you access to the same equipment on more favourable terms.
I spare parts Spare parts specific to each machine — Air Bike, Air Row, Air Ski and Curve Run — can be found in the dedicated section, ensuring continued operation over time without having to replace the entire unit.
The Air Ski Floor Stand (HC004/2 and HC004/2V) is a separate accessory that allows you to secure the Air Ski to the floor and use it in a freestanding vertical configuration, suitable for both professional settings and home gyms.
Why choose Sidea
Sidea has been designing and distributing professional fitness equipment since 1999, with an operational warehouse covering over 4,000 m² and a direct technical support network. The HIIT LINE was developed in response to a clear observation of the Italian professional market: gyms and trainers are looking for robust cardio machines that are easy to maintain over time and have low running costs — not complex electronic machines prone to frequent breakdowns. Sidea is the official distributor for StrongFirst, sponsor of the Summit of Strength and present at FIBO, events that require direct comparison with the highest international standards of performance and build quality.

Pneumatic resistance machines such as the Air Bike, Air Row and Air Ski have no motor: resistance is generated by air compressed by the fan and scales in proportion to the force applied by the athlete. Energy expenditure is higher for the same duration, electricity consumption is zero, and maintenance is significantly reduced compared to motorised treadmills. The Curve Run operates on the same principle: it is the athlete who moves the belt.
-
Yes. The self-regulating air resistance is particularly well suited to active recovery: cycling or rowing at a low cadence produces minimal resistance, allowing you to keep your circulation going without building up fatigue. Many fitness coaches use the Air Bike at 60–70 rpm during recovery blocks between sessions or on deload days.
-
The Air Bike and the Air Row require a base area of approximately 120 × 60 cm, with a recommended working area of approximately 2 × 1.5 m, including space for movement. The Air Ski is more compact in length (around 110 cm) but requires the floor stand for use on the floor. The Curve Run is similar in size to a standard treadmill: a footprint of approximately 170 × 80 cm.
-
Classic HIIT (e.g. 20 seconds of exercise / 10 seconds of rest × 8 rounds), Tabata, EMOM calories (e.g. 10 calories every minute for 10 minutes), AMRAP in conditioning mode, and interval training at defined metabolic thresholds. They are also compatible with athletic training protocols such as repeat sprint ability (RSA) and maximum aerobic power tests.
-
No. The Air Ski is designed to be mounted on the floor stand (HC004/2 or HC004/2V), which secures the machine to the floor and keeps it in the correct position during use. The floor stand is a separate accessory available from the catalogue. Without it, the machine is not stable enough for safe use.
-
The V series (HC001V–HC004V) is available in the Outlet and Promotional Items section of Sidea: these are the same models as those in the HIIT LINE range, but offered under different purchase terms.
