It seems backwards, but all your gains and adaptations from training are made outside the gym. Your recovery strategies, what you eat and when, and the quality and quantity of your sleep, all determine how much you’re going to benefit from your training program. Too much stress, eating crap and a lack of sleep are going to wreck havoc on your mind and body, delaying and terminating any potential gains you might see. Eat real and nourishing foods. Try reducing the amount of stress in your life (family and work) and create healthy sleeping habits to maximize your training results.
