Muscle Loss or Difficulty Building Muscle
Whether you CrossFit, StrongLifts 5x5, P90X, Zumba, or spend endless hours at the gym, all muscle development programs operate on the same principle of progressive overload to stimulate hypertrophy (muscle growth). Repair and growth of your muscle does not occur, however, when you're lifting those weights. Weight lifting is only the growth stimulus. Muscle growth occurs when you sleep. Every elite lifter and world-class trainer will tell you the same thing: you will not grow into the Hulk unless you sleep.
If you don't like how you look naked, or if you've wasted money on gym memberships or home exercise equipment with no visible results, then focus first on improving your restorative sleep! Don't let sleep apnea or poor restorative sleep steal your gains! Get your sleep evaluated today.
