The Role of Sleep in Muscle Growth and Performance
When it comes to building muscle and improving athletic performance, most people focus on training hard and eating right. But there’s one crucial factor that’s often overlooked: sleep.
You can lift heavy, nail your macros, and take all the right supplements but without quality rest, your progress will stall. Here's why sleep isn't just recovery, it's part of the training plan.
Sleep is when you actually build muscle
Muscle growth isn’t just about how much you lift, sleep is what locks in the gains. Without enough quality rest, your body can’t properly release the growth hormones needed for muscle repair, growth and retention. Without enough quality sleep, growth hormone levels drop, making it harder to recover and harder to grow.
Lack of sleep can cause higher stress levels
When you don’t get enough rest, your cortisol levels rise- this is your body’s main stress hormone. Elevated cortisol can reduce testosterone and interfere with muscle recovery, making it harder to build strength and size. In short, this can result in your body breaking down muscle instead of building it.
Sleep regulates your hunger
Not sleeping enough not only throws off your routine, but it can also affect the hormones that control your hunger levels. That means you're more likely to overeat, crave junk food, and derail your nutrition goals. Your body can’t refuel, repair, or regulate energy as efficiently - setting you back even if your training and nutrition are on point.
How much sleep do you really need?
For optimal recovery and performance, you should aim for 7–9 hours per night. While this is the standard, quality matters just as much as quantity. A full night of restless, interrupted sleep won’t support recovery the way deep, uninterrupted rest will. Here’s a few ways to improve your sleep routine:
-
Stick to a consistent sleep schedule
-
Limit blue light (phone, tv, laptop) 1-2 hours before bed
-
Avoid caffeine late in the day
-
Wind down with a relaxing routine (reading, meditation etc.)
Whether your goal is strength, endurance, physique, or all three, don’t underestimate the impact of consistent, high-quality sleep.

Beginners guide to starting a running routine this year
Whether you're looking for a new fitness challenge, gearing up for a 10k run, or simply aiming to get in shape - your running journey starts here!
Running is one of the most accessible ways to get fit, relieve stress, and boost mental health but it can also be intimidating if you’re just starting out. We’ve put together a simple guide to help you get moving safely and confidently this year.
1. Set Realistic Goals
Starting with a goal can make all the difference. Begin with something achievable, like running a specific distance or time, or simply going for three short runs a week. Avoid setting high expectations right away; this will help you stay motivated without the pressure.
2. Start Slowly
A common mistake beginners make is diving in too fast. Start with a mix of walking and running, such as the “run-walk” method. Try alternating a few minutes of running with a minute of walking, gradually increasing the running intervals each week.
3. Invest in Essential Gear
A quality pair of running shoes that matches your foot type and supports your stride can greatly reduce injury risk and enhance comfort. Moisture-wicking clothing will keep you dry, especially if you're running in various weather conditions. Adding a reliable set of headphones for music and a running vest can boost motivation and keep essentials within reach on your runs.
4. Warm Up and Cool Down
Warming up prepares your muscles for the workout and can improve your performance. Start with a 5-minute brisk walk or dynamic stretches. After running, spend a few minutes cooling down with gentle stretching to help prevent stiffness and soreness.
5. Track Your Progress
Using a journal, app, or smartwatch to track your runs helps you see progress over time and keeps you motivated. Start with a baseline run, and gradually push your limits by small increments each week. Seeing improvements, no matter how small, can give you a huge confidence boost.
6. Listen to Your Body
It’s normal to feel some discomfort as you start running, but pain is a red flag. If you feel sharp or persistent pain, take a rest day and allow yourself to recover. Proper rest is crucial for building endurance and strength over time.
7. Stay Consistent
Consistency is key in building a running routine. Aim for small, steady improvements each week rather than big jumps. Finding a running buddy, joining a local park run, or having an upbeat playlist can help you stay motivated on those days when getting out the door feels tough.
8. Celebrate Milestones
Whether it’s your first mile or first week without skipping a session, take time to celebrate! Acknowledging your achievements, no matter how small, can help keep you excited about your progress.
Starting a running routine can be a life-changing decision that builds not just physical fitness but also mental resilience. So, lace up, stay positive, and enjoy the journey—your goals are just a run away!
