ARE YOU DYING DURING WORKOUTS THAT YOU USE TO CRUSH, NOT GETTING LEAN, IS YOUR SLEEP DISRUPTED…LOST YOUR PUNCH HAVE YOU?

To perform your best in training or competition, and to recover afterwards, you need to be properly fueled. That means taking care of the ways and means in which your body produces the energy you need to compete at the highest level.

For short bursts of power, your body depletes its phosphocreatine supply to generate Adenosine Triphosphate (ATP), and contract your muscles as rapidly as possible. Your body can’t move without ATP being used – it’s the “product” your body purchases with metabolic “currency”. Four minutes after a maximal contraction, your body finally replenishes your phosphocreatine, and you’re ready for another maximal contraction.

But if you do multiple efforts at maximal intensity, and you’re not waiting four minutes, your body begins to migrate from the phosphagenic pathway towards the glycolytic pathway. At this point, glucose (blood sugar) is used to generate ATP. Soon afterwards, at about the 3-4 minute mark, your body begins to rely on protein, fat, and carbohydrates to continue paying for ATP. And while your muscles are busy converting your fuel into energy, they’re also producing waste products, like lactic acid, and causing you to sweat, losing methyl donors like Betaine, that are used to help create more ATP. It begins a vicious cycle, causing you to hit the dreaded “wall” – where your body goes into shutdown mode.
