2. What is plyometric training?
This is a type of training in which your own body weight is used as resistance. The exercises are performed
dynamically and involve a stretch and contraction sequence of the muscle fibres. This trains what is known as
reactive strength. This kind of training is based on the muscles’ ability to store energy during a stretching phase
and release it again during a subsequent contraction phase, which produces a more powerful output (comparable
to stretching a rubber band and then releasing it).
3. What to consider during plyometric training
The dynamics – The aim is for the muscle fibres to store more energy during the eccentric stretch phase and
transfer it more explosively to the concentric phase. It is important that the transition period between the eccentric
and concentric phases is short, otherwise the stored energy ‘evaporates’. For squat jumps, for example, you
shouldn’t stay in the squatting position for too long and it’s best to immediately jump in the air again after reaching
the squat.
This training is not just for those at an advanced level. Beginners can also approach this new form of exercise,
as long as they do so step by step and only after they have developed the basics in terms of endurance, strength,
mobility and coordination. They can then increase the intensity gradually.
The workout – The maximum number of repetitions per workout depends on the athlete’s training level. Beginners
should ideally do 80–100 repetitions, advanced exercisers 100–120 and pros 120–140. We also recommend only
two training sessions per week, as the nervous system can take up to four days to recover.
The warm-up – The muscles must be prepared, otherwise you risk overstretching, overusing or tearing your
muscles. The risk of injury to joints, tendons and ligaments also increases without a proper warm-up.
The correct execution – This reduces the risk of injury as the muscles, tendons and joints get used to the dynamic
load when you gradually introduce new movement sequences to your training routine. The risk of injury increases
enormously with incorrect and inappropriate execution.
4. Warnings
•All Sport-Thieme plyo boxes are designed for exercising and should only be used as intended.
•Modifications of any kind will compromise safety and render the warranty void.
•The soft plyo boxes should not be used on smooth floors including wood, concrete or tiles.
5. Regular inspection
•Perform a visual inspection regularly.
•Tighten the screw connections routinely.
•Check the equipment for any damage and replace worn parts.
•Due to continuous quality control of our products, technical changes may occur which could lead to minor
alterations to the instructions.
6. General notes on training
•Consult your doctor before commencing your training, particularly if you have any pre-existing medical
conditions such as diabetes, spinal complaints or heart problems, but also if you are new to exercising or
have not been active for a prolonged period.
•You should warm up before each workout to help protect muscles and tendons from injury. It’s also very
important to carry out the exercises correctly in a slow and controlled manner. Always breathe evenly and
