Description
The Spirit i-Strength IS-2003 is an intelligent lower-body strength solution that combines leg extension and leg curl into a single, compact smart machine. Designed for gyms, wellness centers, and rehabilitation environments, it replaces traditional weight stacks with servo-motor electronic resistance, delivering smooth, quiet, and highly controlled training. Micro-adjustable loads in 0.5 kg increments ensure precision, safety, and consistency for users of all fitness levels.
Engineered for versatility, the IS-2003 features four scientifically supported training modes: Pure for traditional strength training, Eccentric for enhanced muscle fatigue through negatives, Isokinetic for constant-speed functional training, and Elastic for power and explosive movement development. These modes allow the machine to support general fitness, performance training, and rehabilitation applications within one platform.
User interaction is simplified through a 10.1-inch touchscreen console that clearly displays load, time, and progress data. The guided interface helps users train confidently while enabling operators to deliver a consistent, premium workout experience. With open connectivity via Wi-Fi and Bluetooth, this machine integrates seamlessly with the Spirit+ Connect ecosystem and Spirit Club App, allowing workout data tracking, personalization, and member engagement.
For facility operators, i-Strength represents a smart, future-ready investment. Its premium build quality, certified to global standards (CE 60335 / EN 957 / FCC), enhances facility appeal while optimizing space and member engagement. By combining intelligent technology with practical strength training, the IS-2002 delivers a results-driven, safe, and enjoyable experience for every user while strengthening the operator’s product portfolio.
Features
Pure Resistance
Traditional weight training for hypertrophy. Building muscle takes consistent repetitions, and now i-Strength is your training partner, right by your side. It adjusts your weights, challenges you and keeps you motivated, whatever your goals.
Eccentric Load
Resistance increases on the return movement to build strength. If you didn’t know better, you might think eccentric training was a gym secret. Now meet i-Strength, your new training partner. Nothing challenges and motivates you better through those heavy negative drop-sets.
Isokinetic Control
Constant speed regardless of the force you apply, for safety. It’s no wonder athletes turn to isokinetic training for rehabilitation. It builds the joint integrity needed to get back to performance quickly. i-Strength is the tool and the leader that creates this environment, with the bi-directional resistance and safety controls needed for success.
Isokinetic Mode
Resistance increases as your range of motion increases, building explosive power. It works like a smart rubber band: the further you pull, the greater the resistance. This snappy feel activates your nervous system and your fast-twitch muscle fibers. When you reach the point where you can’t push any further, you are training isometrically, which is especially valuable for senior rehabilitation.
Connected Console &
Spirit+ Club App
Log in to the touchscreen console in seconds by scanning a QR code with the Spirit+ Club app, available on the App Store and Google Play. Your progress follows you to your phone, where you can track total reps, see a 30-day muscle map of your work distribution, and review daily, weekly or monthly training volume.
Next-Generation Commercial-Grade Digital Resistance
A smart console paired with a fully enclosed resistance module, giving you a premium, durable machine built for commercial use. It features durable, matte black pads with an embossed carbon-weave design, a heavy-gauge steel frame with a high-quality electrostatic powder coat finish, and steel feet with rubber foot covers. A max user rating of 159kg (350lb).
