"Your heart rate is really accelerated. You're getting more CO2 than oxygen," said Sarbou-Jubert. "That exchange of air flow is not good."
If you cannot breathe properly, stop exercising immediately. Once your system has rebounded and you begin to feel better, if you're going to return to your exercise regimen, simply tone it down, performing each exercise more slowly.
• Stay hydrated. Staying hydrated throughout an exercise routine will increase flexibility and replace the water you lose by sweating. While some might feel this will counteract any weight loss, losing water weight is not the type of weight loss you should be aiming for. Be sure to drink lots of water before, during and after workouts.
Sarbou-Jubert added those who do not like water shouldn't look to sports drinks such as Gatorade or Powerade, as they will add to the calorie intake.
"Powerade or Gatorade is there to replace electrolytes," she explained. "It has a lot of replacement stuff. Bu,t when you're an average Joe in the gym, and you're coming in and you're doing your work out and you're running and you're only in here for an hour, you're giving yourself a lot of stuff that you really don't need."
• Remember the wisdom of mom and dad. Nearly everyone who ever went to the beach as a child recalls mom and dad advising them to stay out of the water after eating. That same advice you heard as a child is still applicable today as an adult. While it's acceptable to go for a light walk after a small meal, avoid strenuous exercise for at least two hours after eating a big meal.
Sarbou-Jubert explained the blood will flow away from the stomach, where it is needed to process the food, and flow to whatever part of the body that is being worked out.
