What exactly is the OsteoTrainer®?

The OsteoTrainer® is a revolutionary "loop trainer" system for isometric and dynamic full-body workouts that revolutionizes exercise. Unlike suspension trainers that require attachment points, all you need is your body, 1 m² of space, and your OsteoTrainer®.

How does the OsteoTrainer® differ from conventional strength training?

The OsteoTrainer® follows a medically inspired stimulation concept instead of external weights and isolated trained muscles:

• Stimulus instead of stress: Your own muscle tension creates the resistance – without impact or shear forces.
• Systemic training: functional muscle chains instead of isolation exercises.
• Safe & adaptable: Intensity according to your level – ideal for rehab, seniors, children, athletes.
• Independent of time and place: 5-10 minutes are enough – no studio, no changing equipment.
• Systemic effect: Strengthening of strength, bones and tendons.

What materials does the OsteoTrainer® consist of and
where is it produced?

The OsteoTrainer® is produced in Germany
and consists of patented, ergonomic handles and color-coded
Nylon loops, nylon foot loops and a nylon torso strap.

Is the OsteoTrainer® durable and resilient?

Absolutely. Our nylon loops and handles are designed for maximum strength—comparable to a car seatbelt. One of our customers even reported towing his car with the OsteoTrainer®.

Important NOTE:
Please note that the OsteoTrainer® was developed exclusively for training purposes. Always use it as intended and ensure correct posture and controlled exercise execution.

Is there a guarantee?

Yes, we offer a 2-year warranty against defects in materials and workmanship when used properly.

How does the training affect my body – and what is the difference between isometric and dynamic exercises?

Isometric (static)

Holding positions create maximum muscle tension without movement. Benefits: Development of strength, posture, bone and tendon strengthening, gentle on the joints.

Dynamic (mobile)

Controlled pulling and pushing movements at 50–80% of maximum strength activate the cellular metabolism in the muscle by:

• Capillarization: Formation of new fine blood vessels for better oxygen and nutrient supply.
• Mitochondrial formation: More “power plants” in the muscles for longer performance.
• Neuromuscular effect: Your nervous system learns how to optimally coordinate muscle groups – for greater stability and efficiency.

How long should I train to see results?

We recommend three 5-10 minute sessions per week to achieve noticeable improvements in posture, body tone, and strength after two to three weeks. Studies show measurable strength gains after just a few sessions. Some of our clients, like us, now train with the OsteoTrainer® for about five minutes daily.

Which muscle groups are trained – and why
the core muscles are not mentioned separately?

The OsteoTrainer® always activates entire muscle chains—never just one muscle in isolation. Your core muscles automatically remain active during every exercise, as all movements require an upright, stable posture.

What do I need to consider when training?

• Clean posture: shoulder girdle active, torso stable
• Focus on tension and correct movement sequence
• Controlled breathing: No pushing
• Individual intensity: Start moderately and increase
• Quality over quantity: Your body responds to a few good stimuli, not to many bad ones.

Do I need to warm up before training?

No, classic warm-up is not
required. You control the intensity yourself. Optionally, you can add 1–2 minutes
mobilize if it makes you feel better.

How do I adjust the OsteoTrainer® correctly?

The OsteoTrainer® is ready to use right away and requires no adjustment. Simply change your grip and you can switch between exercises in a flash.

Is there an app or digital instructions?

Yes – the free OsteoTrainer® app contains all the exercises, workouts, explanatory videos, and training tips. You'll also receive our printed workout manual with your order, which offers the same level of detail as our app.

Can I also with physical limitations
train?

Absolutely. The OsteoTrainer® is also suitable for back problems, osteoarthritis, disc problems, after surgery, or for mobility restrictions. You control the load yourself – anything that doesn't hurt is good for you and your movement.

Important NOTE:
Please consult your treating physician or physiotherapist in the event of acute inflammation, fractures, or complex orthopedic diagnoses.

Is training with the OsteoTrainer® safe?

Yes – you work exclusively with your own muscle tension, without external weights or impact forces. The movements are biomechanically tested and promote healthy movement patterns. The SAFE³ principle ensures safe training with your OsteoTrainer® at all times.

Can I exercise if I have health problems?

Yes – Dr. Dr. Kaufmann also developed the system for therapeutic purposes.

Osteoarthritis & joint problems

Isometric stimuli strengthen muscles and surrounding connective tissue without damaging the articular cartilage through shock loads.

Osteoporosis & bone loss

Static training generates high local tensile and compressive forces, which promote bone formation via osteoblast activation (Wolff's law).

Chronic back pain & poor posture

Targeted activation of deep-lying postural and supporting muscles stabilizes the spine and relieves pressure on intervertebral discs.

Postoperative rehabilitation

Since no microtraumas occur, gentle but effective loading is possible even in the early stages of rehabilitation.

Bedridden people

Exercises can also be performed while lying down – although they do not reach the full intensity of standing, they still offer safe and efficient training for people with limited mobility.

Important NOTE:
Please consult your treating physician or physiotherapist in the event of acute inflammation, fractures, or complex orthopedic diagnoses.

What does the SAFE³ concept mean?

SAFE³ summarizes our six development principles that go beyond pure safety:

• Safe: No impact or shear forces, no forced postures, self-power control
• Age-appropriate/Adaptable: Scalable intensity for each user group
• Flexible: Mobile, can be used without power or mount – anytime, anywhere
• Effective: High muscle tension, osteogenic stimulus, metabolic activation
• Efficient: 5–10 minutes per session, no need to change equipment
• Simple: Intuitive handling, quick to learn

How does training affect bone density and ligaments?

Bone density (osteogenesis)

Mechanical stimuli activate osteocytes, which stimulate bone formation via osteoblasts and inhibit osteoclasts. The result: denser, more resilient bone tissue.

Ligaments & tendons (collagen synthesis)

Isometric holding phases put tension on ligaments and tendons, and fibroblasts produce increased type I collagen. Cross-linked collagen fibers increase tensile strength and elasticity.

How do isometric and dynamic training complement each other?

Isometric

Immediate, high-intensity muscle and bone stimulation without joint movement. Focus on strength and stability.

Dynamic

Alternating muscle tension improves blood circulation and metabolism, promotes capillary and mitochondrial formation and provides the optimal stimulus for muscle growth by exhausting the muscle cells.

Joint effect

Muscle growth and strengthening, better joint control, increased stability, lower risk of injury.
This mixture increases the density of your bones, strengthens your ligaments, and grows and strengthens your muscles – for greater mobility and health in everyday life.

Is the OsteoTrainer® suitable for children?

The OsteoTrainer® is even ideal for children, as it helps them develop a stronger body awareness and improve their motor skills. For children up to 1.60 m tall, there's the OsteoTrainer® Junior – age-appropriate and safe.

Does the OsteoTrainer® help with back pain or
Postural weaknesses?

Yes – isometric exercises strengthen the deep muscles, correct imbalances and stabilize the spine.

Can I also lose weight with the OsteoTrainer®?

Yes, indirectly through metabolic adaptations:

Afterburn effect (EPOC): Your body continues to burn calories after training.

Increased basal metabolic rate: More muscle mass means more energy consumption at rest.

Important:
For sustainable weight loss, an adapted and conscious diet is crucial.
