1. Aqua HIIT

Aqua HIIT is a highly effective method of high intensity low impact exercise that leverages the natural resistance of water to provide a challenging cardiovascular workout while minimizing stress on your joints. It combines the principles of high-intensity interval training (HIIT)—short bursts of vigorous activity followed by brief recovery periods—with the unique properties of an aquatic environment. The buoyancy of the water supports your body, reducing impact, while its density creates a resistance 12-14 times greater than air, making every movement more demanding. This makes Aqua HIIT an excellent choice for anyone looking to improve fitness without putting excessive strain on their body.

Aqua HIIT workouts are typically performed in chest-deep water, allowing for a full range of motion while maintaining the benefits of buoyancy. They often incorporate traditional HIIT timing protocols, such as Tabata (20 seconds on, 10 seconds off, repeated for 8 rounds), combined with water-specific movements like running in place, jumping jacks, cross-country ski motions, and high knees. Specialized aquatic equipment, such as paddles, kickboards, and noodles, can be used to further enhance the intensity and target specific muscle groups. This adaptability makes Aqua HIIT a suitable training method for aspiring Hyrox competitors, busy professionals, former athletes, home gym users, and fitness enthusiasts alike.

However, kettlebell flow training does have its drawbacks. It requires technical proficiency in foundational kettlebell movements like swings, cleans, and snatches. Mastering the smooth transitions between exercises in a flow also presents a learning curve, and improper form can increase the risk of injury, particularly lower back strain if core stability is not maintained. While highly effective, achieving maximum heart rate comparable to plyometric HIIT can be more challenging with kettlebell flows. Finally, purchasing quality kettlebells can represent a significant initial investment, especially if building a full set.

Examples of established kettlebell flow systems and programs include Onnit’s Six Flows System, which combines kettlebell exercises into metabolic circuits, and The Primal Kettlebell Course by StrongFirst certified instructors. You can also explore Steel Club and Kettlebell Flow workshops by Mike Fitch or adapt the ‘Simple & Sinister’ protocol by Pavel Tsatsouline into flows.

To get started safely and effectively, master individual kettlebell movements before attempting to combine them into flows. Begin with a lighter kettlebell than you would typically use for single exercises and prioritise maintaining rhythmic breathing throughout the flow, especially during the more explosive ballistic movements. Start with short flows combining 2-3 exercises before progressing to longer, more complex sequences. Practice ‘parking’ the kettlebell safely between sets and try the ‘Turkish Get-Up to Windmill’ flow as a beginner-friendly sequence.
