The power, hard work and sense of accomplishment after BJ’s is just unbeatable!!!
BJ’s require A LOT of energy because they are highly intense. They use the WHOLE body and will activate nearly every muscle, which is why BJ’s burn a heap of calories in a single session and can help you loose weight.
The POWER and SPEED that comes from a BJ will help you increase your strength. When you follow an eccentric contraction (muscle lengthening) with a concentric contraction (muscle shortening) your muscle produces greater force and this is where the power and speed utilised in a BJ comes from.
The only disadvantage with BJ’s is the high risk of injury. I have never personally seen anyone hurt himself or herself during a BJ but because of the intensity and impact on the body it is quite common, so it is very important your BJ’s technique is on point. If you are a beginner it is important to start with low volume and gradually progress once you have built up strength.
It is safe to do BJ’s 2-3 times a week but make sure you begin with a light 10 minute warm up to increase blood flow to help your muscles function properly and to prevent injury.
So make sure you add box jumps to your workouts – an exercise I LOVE!
