Final answer:
You should inhale during the recovery phase and exhale during the lift or exertion phase of the exercise during weight training.
Step-by-step explanation:
During weight training, it is generally recommended to inhale on the recovery phase of the exercise and exhale on the lift, or the exertion phase. This breathing technique helps to stabilize the core and provides the necessary oxygen to the muscles during the strenuous activity. It's also a crucial part of maintaining proper form and safety during resistance exercises. For instance, when doing a bicep curl, you would inhale as you lower the weights (recovery) and exhale as you curl them up (lift).
During weight training, it is important to remember to exhale on the effort or lift and to inhale on the recovery phase of the exercise.
For example, when performing a bench press, you should exhale as you are pushing the weight up and inhale as you are lowering the weight back down.
Inhaling during the effort phase of the exercise can cause an increase in intra-abdominal pressure, which can lead to a decrease in stability and potential injury.
