Kris's Tips for High Intensity Training:
NEVER sacrifice intensity for form.
Always make sure you have proper FORM before increasing intensity.
When training at high intensities, keep an eye on your ENERGY level and be sure to get proper RECOVERY.
Work just as hard on your NUTRITION plan as you do in your workouts.
Always carry a HEALTHY SNACK in your gym bag just in case you are running low on energy. This can be a bag of almonds or an organic dried fruit and nut bar.
