Gymstick Crankbike x4 is the first home exercise bike with pedals also for hands. The bike
can be used just for pedalling with legs but the aerobic training will be even 40 % more
efficient if the pedalling is performed both with legs and hands.
Exercising with Cranbike x4 develops the overall aerobic condition. Pedalling with legs and
hands simultaneously improves the muscle endurance, strengthens the core musculature
and burns calories more effectively and comprehensively than pedalling a normal exercise
bike.
Pedalling with the hands only will strengthen the muscles of the upper body and improve the
metabolism of the neck and shoulder area.
Crankbike x4 is designed for all fitness enthusiasts from beginners to persons in top
condition.
NB! It is not recommended to use the upper body pedal unit continuously for over 30
minutes with the maximum resistance level.
The cranks of the hand pedal unit and the resistance adjustment knob may get overheated if
used with max resistance for over 30 minutes.
The manufacturer disclaims any damages/injuries caused by knob’s metal parts of the hand
pedal unit if they are overheated due to too long pedalling time with max load.
Pauses of at least 5 minutes after 30 minutes continuous pedalling with hands are
necessary.
