Fast shipping Australia-wide, with local pickup available from our Keysborough warehouse in Melbourne’s south-east.

Why Cardio Training Matters

Cardiovascular exercise is foundational to health, performance, and longevity. Regular cardio training improves VO2 max, heart health, metabolic efficiency, and recovery capacity between strength sessions. Research published in the American Heart Association’s Circulation journal recommends at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity per week for adults. The right cardio machine makes hitting that target sustainable, low-impact, and measurable.

Rowing Machines

Rowing is one of the most complete full-body cardio modalities available — engaging approximately 86% of the body’s muscle groups in a single stroke, according to Concept2. It combines cardiovascular conditioning with posterior chain strength work, making it ideal for athletes and general fitness users alike.

• Concept2 Model D (Black) — the world’s most widely used rowing ergometer. Used in CrossFit boxes, elite rowing programs, and rehabilitation centres globally. PM5 performance monitor, foldable frame, and universal compatibility with Concept2’s online logbook.
• Tempest Air Rowing Machine — a commercial-grade air rower delivering natural, resistance-proportional feel. Ideal for HIIT programming, circuit training, and facilities seeking a robust alternative to the Concept2.

Key exercises: steady-state rowing, interval sprints (e.g. 500m repeats), pyramid intervals, and team relay workouts.

Ski Ergs

The ski erg is an underutilised but highly effective upper body and core cardio tool. It mimics the double-pole motion of cross-country skiing, driving high caloric output while sparing the lower body — making it ideal for injury management and upper body conditioning. A 2017 study in the Journal of Strength and Conditioning Research confirmed the ski erg’s effectiveness for high-intensity interval training and aerobic capacity development.

• Concept2 Ski ERG + Stand — the complete freestanding setup for commercial and home gym use.
• Concept2 Ski ERG (No Stand — Wall Mountable) — space-saving wall-mount option for smaller facilities or home gyms.
• Concept2 Ski ERG Stand Only — convert a wall-mounted unit to freestanding.
• Tempest Ski Erg and Stand — commercial-grade ski erg with integrated stand at a competitive price point.

Key exercises: double-pole intervals, alternating arm pulls, ski erg Tabata (20s on / 10s off), and 1km time trials.

Air Bikes

The air bike is one of the most demanding cardio tools in any facility. Resistance scales infinitely with effort — the harder you push, the harder it gets. The simultaneous push-pull arm action and leg drive make it a true full-body conditioning tool, widely used in CrossFit, HIIT, and military fitness programs.

• Tempest-XT Commercial Magnetic Air Bike — a commercial-grade air bike with magnetic resistance augmentation for smoother feel and quieter operation. Built for high-frequency use in commercial environments.

Key exercises: Assault bike intervals (e.g. 10 calories for time), 30/30 HIIT, max calorie sprints, and aerobic base building at low RPM.

Treadmills

Treadmills remain the most popular cardio machine globally, offering accessible, programmable running and walking for all fitness levels. Research from the American College of Sports Medicine (ACSM) consistently identifies treadmill running as one of the highest calorie-burning cardio modalities per hour.

• APXMAX Stride Commercial Treadmill — a heavy-duty motorised treadmill built for commercial use. Suitable for gyms, hotels, and high-traffic facilities requiring continuous operation.
• Tempest Runner Non-Motorised Curved Treadmill — a self-powered curved treadmill that activates more posterior chain musculature than motorised alternatives, as supported by biomechanical research comparing curved and flat treadmill gait. No motor, no electricity, no speed cap.
• Vision T600 Treadmill — a premium motorised treadmill from Vision Fitness, featuring a cushioned deck, intuitive console, and whisper-quiet motor. Ideal for home gyms and boutique studios.

Key exercises: steady-state runs, incline walking (fat-burning protocol), sprint intervals, and walk-to-run progressions for beginners.

Exercise Bikes

Low-impact and joint-friendly, exercise bikes are suitable for all ages and fitness levels. They are a preferred rehabilitation tool and an effective aerobic conditioning machine for daily use. The Better Health Channel (Victoria) highlights cycling as one of the best low-impact exercises for cardiovascular health.

• Concept2 Bike Erg — the gold standard in performance cycling ergometers. Uses the same PM5 monitor as the Concept2 rower and ski erg, making it ideal for data-driven training and cross-training programs.
• Vision U60 Upright Exercise Bike — a commercial-quality upright bike with a natural riding position. Suitable for cardio conditioning, warm-ups, and active recovery sessions.
• Vision R60 Recumbent Bike — a recumbent design that reduces lumbar and hip flexor strain, making it ideal for older users, rehabilitation, and extended low-intensity cardio sessions.

Key exercises: steady-state cycling, sprint intervals, cadence drills, and low-resistance active recovery.

Elliptical Trainers

Ellipticals deliver a full-body, low-impact cardio workout that mimics the natural motion of running without the joint stress. Studies published in the Journal of Orthopaedic & Sports Physical Therapy confirm that elliptical training produces similar cardiovascular responses to treadmill running at significantly lower impact forces.

• Vision S60 Elliptical Trainer — a commercial-grade elliptical with a smooth, natural stride and upper body arm handles for full-body engagement. Suitable for home gyms, studios, and commercial facilities.

Key exercises: forward and reverse stride intervals, upper body isolation (hands-free), incline resistance progressions, and steady-state cardio.

Stair Climbers

Stair climbing is one of the highest-intensity low-impact cardio modalities available. It targets the glutes, quads, hamstrings, and calves while driving significant cardiovascular demand. Research from the European Journal of Applied Physiology found stair climbing to be highly effective for improving VO2 max and lower body muscular endurance.

• Tempest Stair Climber Machine — a commercial-grade step mill delivering continuous stair-climbing motion. Ideal for conditioning, fat loss, and lower body endurance work in commercial gyms and high-performance facilities.

Key exercises: steady-state climbing, interval step sprints, lateral step variations, and weighted vest stair climbs.

How to Choose the Right Cardio Machine

The best cardio machine is the one you’ll use consistently. Consider these factors:

• Joint health — for low-impact options, prioritise the recumbent bike, elliptical, or rower
• Space — wall-mountable ski ergs and foldable rowers suit smaller home gyms
• Training goals — for maximum caloric output and conditioning, the air bike, curved treadmill, and stair climber lead the field
• Data and tracking — Concept2 machines (rower, ski erg, bike erg) share the PM5 monitor and integrate with the Concept2 Online Logbook for performance tracking
• Commercial durability — Tempest and APXMAX machines are built for continuous commercial use; Vision Fitness suits boutique studios and premium home gyms
