As mentioned, your muscles require rest. Sleep is when your body recovers, repairs and rebuilds. Quantity and quality is important when it comes to sleep, so do your best to maintain a consistent sleep schedule. Some tips to improve your sleep quality include: sleeping in a cool dark room, turning off electronics, exercising during the day, avoiding caffeine late at night and taking a warm bath before bed. Having a healthy lifestyle is about building consistent habits and finding your balance. Contact the awesome team at Crux Fitness Gyms in Richmond BC if you want help reaching your fitness goals.
