The i-Strength series is an innovative line of strength equipment with an electronically adaptive resistance system. In contrast to classic devices with plug-in weights, the resistance here is generated using a motor and controlled precisely. The result: an exceptionally consistent, precise and effective training experience. Thanks to the intelligent control and the integrated 10.1" (25.65cm) touchscreen console, training parameters can be precisely controlled, analyzed and evaluated - for maximum control and efficient, modern strength training.
Advantages of the i-Strength device series:
- extremely smooth movements
- instantly adjustable resistance
- reproducible training conditions
- significantly more training variety
- no weight stacks – quiet, low-maintenance, modern
- extremely even resistance for optimal movement quality
- quick adjustment without replugging
- Measurability & reproducibility of every training session
- Versatility: strength, rehab, explosiveness in one device
The 4 training modes at a glance
1. Pure (classic resistance - traditional weight training) - The “Pure” mode corresponds to classic strength training with consistent resistance. Comparable to classic devices – only more precise and controlled.
Ideal for:
- Muscle building (hypertrophy)
- general strength training
- Beginners & advanced
2. Eccentric (eccentric training - increases the resistance during the backward movement) - Here the negative phase (yielding movement) is specifically reinforced. Eccentric training is considered one of the most effective methods of strength training. Eccentric strength training is a technique that focuses on the lowering or stretching phase of an exercise. Often referred to as the “negative” movement. To increase strength, it is necessary to tire the muscles. Eccentric training is valuable for achieving muscle fatigue.
Advantages:
- particularly effective muscle building
- higher strength gains
- more intense training stimuli
3. Isokinetic (constant speed regardless of the force applied) - The resistance adjusts so that the movement is always carried out at a constant speed. In isokinetic exercises, the speed of movement remains constant, but the resistance varies. As a rule, special equipment is required for this. Effective in improving functional performance and often used to restore mobility.
Advantages:
- maximum control
- high security
- ideal load control
- Particularly suitable for: rehabilitation, physiotherapy, training that is gentle on the joints
4.Elastic (dynamic resistance - the resistance increases as the stretch increases) - The resistance increases progressively - similar to a resistance band. Elastic training is a form of strength training that uses fast-twitch muscle fibers to exert force quickly. Incorporating elastic training increases strength, improves reaction time and reduces the risk of falls in older people.
Advantages:
- Improving explosive power
- Activation of speed strength (fast twitch fibers)
- sport-specific training
- Ideal for: Athletes, functional training, performance training
Areas of application:
1. Physiotherapy & Rehabilitation
- safe, controlled movements
- ideal load control
- reproducible training programs
- Perfect for medical training concepts
2. Fitness studios & boutique studios with a care concept
- modern alternative to classic devices
- high training quality
- attractive for demanding customers
3. Personal training
- individual training control
- versatile training methods
- ideal for supervised training
4. Athletes & ambitious exercisers
- Explosive power & performance
- eccentric training
- sport-specific stimuli
Equipment Inner/Outer Thigh:
- Adduction and abduction movements enable targeted training of the inner and outer thigh muscles while keeping the body stable in the sitting position. The guided movement ensures isolated strain on the hip and leg muscles and reduces unwanted evasive movements.
- Intelligent controls and the integrated 10.1" (25.65cm) touchscreen console
- The dual function allows you to train the inner and outer thighs in one device and at the same time saves space on the training area.
- The quick change between Inner Thigh (adduction) and Outer Thigh (abduction) is easy and efficient from the sitting position.
- Large, ergonomically shaped thigh pads and stable footrests ensure a high level of training comfort and a safe position throughout the entire movement.
- The stable sitting position supports clean execution of movements and enables targeted activation of the hip muscles.
- The mechanical resistance system i-Strength enables extremely even training.
- Electromechanical servo control mechanism provides standard traditional, eccentric, isokinetic and elastic training.
- The system based on smooth servo motors ensures a friction-free training experience. Thanks to the digital load calculation, it offers incomparable calm and uniformity that cannot be achieved with conventional weight training.
- Precision engineering. Proven reliability. Tested to 2 million cycles to ensure consistently reliable resistance performance.
- Minimum resistance 5kg - maximum resistance 100kg
- Dynamic color feedback - the integrated LED light bar changes color dynamically as the load increases, making it possible to immediately identify training zones.
- Connect App – update your training data – with a simple login in the app, your entire training is automatically saved. This visual representation of your progress not only shows your development, but also creates a personal “Strength Resume,” creating a strong, data-based connection between the member and your institution.
- Real-time monitoring – cloud-based management allows operators to monitor device status and usage load in real time. This ensures equipment remains safe and functional at all times without the need for manual controls, while significantly increasing operational efficiency through precise data analysis.
