James Shapiro, NASM-certified personal trainer and owner of Primal Power Fitness, wants beginners to believe in the process. "Your change, whether it be body composition, strength-related, or performance-designed, takes time," he reassured. He added that everyone's bodies react differently to workouts because of genetics, but the one thing that'll ensure you'll see results is putting forth effort in all aspects of your journey. "This means during your workouts, in the kitchen, improving your stress management, sleep, and recovery that can stagnate progress," Shapiro said.
