The Exerfly Portable is made in New Zealand using a dense fibreglass impregnated foam core sandwiched between fibreglass sheets. Built to last, the fibreglass reinforced dense foam in the Portable ensures the equipment can withstand high loads of force. It is then painted with epoxy paint, similar to high strength glue, adding to its robustness and balance. The fibreglass has a breaking strain of 500kg (1100lbs). The shaft is made from 7075 aluminium alloy, so it's very lightweight and strong.

Without the flywheels, rope guide and harness, the Exerfly Portable weighs 7.5kg/16.5lbs. Different accessories can be added to the Portable depending on what you’re wanting to train and where you’re travelling. These accessories can be stored in a suitcase or a sports bag. Accessory weight: Flywheel 0.1 kg·m² - 5kg: red flywheel is used for big muscle groups. one to two red flywheels are for high forces at high speeds. Any flywheels added to that are for performing at a lower speed with high forces and increased resistance, mostly used by powerlifters. You can fit up to 7 red flywheels on the Exerfly Platform, with max inertia of 0.7kg-m2 (almost double anyone else in the industry). Flywheel 0.05 kg·m² - 3.5kg: blue flywheel is used for higher force loads and at a quicker speed Flywheel 0.025 kg·m² - 2.5kg: yellow flywheel is used to recreate different sporting movements and is used for smaller muscle groups to train at low force high speed e.g. glutes Rope clamp - 1kg Harness - 1kg We would recommend purchasing all of our flywheels in order to target a wide range of movements and exercises. The more red flywheels you use, the higher force you can achieve at a slower speed. For home users, we would recommend purchasing two red flywheels. For weight lifters and powerlifters, we would recommend going for four-six red flywheels to train at a high force load with lower speed and constant resistance.

The Exerfly Portable packs down to fit in a suitcase with room to spare in 2 minutes or less. We initially designed it for New Zealand sporting teams as a piece of equipment that could be taken overseas without having to use outdoor spaces and gyms. It’s an entire gym in a box that can be used to train strength and conditioning, rehabilitation and maintenance.

The Black Caps, the New Zealand National Cricket team and current world champions, as well as New Zealand Snow Sports and New Zealand Olympics, used it when travelling around the world because they can't guarantee good gym facilities in the countries they visit. If travelling with a group, you may want to distribute the Flywheels between a few people to spread the weight or take them as hand luggage.

With the Portable, you can perform a wide range of exercises for both upper body, lower body, and rotational movements, which are illustrated in the video tutorials. This includes any exercises you can do with the Platform (except double-handed exercises) or Rack Mount, as the centrepiece can be fixed to any vertical structure (such as a pole, a tree, or a squat rack) to transform the Portable into a vertical-mount.

The in-built Sensor and Exerfly app is not included in the price of the Portable, but the Sensor can be added-on as an API or athlete management system for effortless accountability. We would recommend adding the Sensor as it is hugely beneficial for all users, regardless of discipline or abilities. It must be added at time of purchase, otherwise you will need to send your equipment back to our New Zealand manufacturing team at your own cost.

You can fit up to 7 red flywheels on the Exerfly Portable, with a max inertia of 0.7kg-m2 (almost double anyone else in the industry).

The Portable has been tested by a range of different athletes, sports teams, and strength training professionals, including the Crusaders Rugby Team and several athletes from the NZ Olympics. It has never broken, and can withstand up to 500kg of weight.

The Portable Mounting Kit can be attached to any vertical structure such as a pole, tree or squat rack. The Slider can be attached to a squat rack, to ease the transition between high and low exercises, making workouts faster and more efficient.

The Portable rope clamp was designed to withstand up to 15000N of force. It is designed to be slid up and down the rope while you go between different movements/exercises. It can be used in a group setting as the clamp can be adjusted whilst alternating between different people. Depending on the type of training you're doing, if you leave some slack in the rope, there will be a pause in the transition from the concentric to the eccentric movement, but if the rope is left tight then there won't be any pause during the transition from eccentric to concentric.

The Exerfly Portable is widely used as a convenient all-in-one training solution. It can be packed down into a suitcase when travelling and does not require outdoor spaces or a gym to be set up. Furthermore, a wide range of exercises can be performed using the equipment in order to recreate real sporting movements. For example, football teams use the Portable after a game, whilst their players are still warm, to train and fit in their workouts before resuming travel. The Portable is perfect for all users on the road, as it saves you time from having to go to different training facilities.
