Blood Flow Restriction Training is a new and an unique training technique that uses the concept of working out “smarter not harder”. In this, low intensity excercises are done and gives the same result after doing high intensity excercises. It plays an important role to keep the body fit during an active recovery week. It is beneficial for those individuals who are not able to lift heavy weights, not able to do heavy intense excercise, osteeporotic individuals or after surgery.In this, a tourniquet or an elastic band is used near to the muscle that is being trained. It can be applied to either upper limb ( arm) or lower limb( thigh). Tourniquet reduces the blood flow to that particular area.After applying the tourniquet, resistance excercise at a low intensity is done to train the muscles.It creates the same muscle environment that high intensity excercises does.It is used in recreational training and athletic training to obtain muscle hypertrophy.It helps in increasing muscle size faster than regular strength training, gives the same beneficial muscle effects , prevents muscle loss in immobile patients , gives less stress to tendons or joints while lifting
