My Favorite Things #4 Stability Ball
If you spend a fair amount of time at a desk, your posture would benefit from using a stability ball instead of a chair.
You end up sitting up straighter, which results in your lungs and diaphragm not being compressed.... this results in your ability to take deeper breaths and get more oxygen to your brain.
You already know that if your body and brain is getting more oxygen, you will have better cognition and increased energy.
