Breathing Exercises

Observe the way you breathe when doing strength exercises. Holding your breath too long at the difficult phase of the lift puts a lot of pressure in the chest area, preventing oxygen-rich blood to reach your brain, which results in nausea. To counter this, try to exhale slowly during the most difficult phase of the lift and inhale on the easy phase. Being hungry during a workout can also cause nausea so make sure that you eat at least two hours before your workout and keep yourself hydrated.
