Answer:
Circuit training is a training where, in rapid succession, a person performs multiple different exercises with little or no rest among them.
Increased risk of injury.
A person generally performs eight to 10 different exercises in circuit training.
Because an exercise switches between different movements and intensities, a range of exercises will increase the possibility for injury.
Additional room, preparation and facilities.
In your gym, the quality of room and facilities will be a factor in deciding that activities will include your training.
Nonetheless, taking a group fitness circuit class can solve this problem.
Most gyms offer circuit courses where all the installation and training are performed by the instructor.
