Holding your breath is bad. The main reason is your body needs oxygen to workout properly. As you hold your breath you build up your CO2 in your body which will cause you to fatigue faster. Some of my clients either like to count their reps which helps them breath or during your contraction of the muscle breath out and when you relax breath in. So breathing will help you last longer in your workouts.
Decreasing the number of times you breathe allows the amount of CO2 in your body to increase again from tissue metabolism (CO2 is an end product of tissue metabolism). As a result you can hold your breath longer at this time. CORRECT ANSWER: No you can not! When your under water your brain tells you when you need to breathe so if you hypervetilate you loose a lot of the CO2 in your blood.
