This Is How Many Rest Days Experts Say You Need Per Week

Strength Training: 2-3 Days

The magic formula, according to Noam Tamir, CSCS, founder of TS Fitness, is three days of strength training, two days of cardio, and two days of active rest per week.

Strength training days are absolutely crucial for maintaining a healthy weight. In addition to forming and shaping a strong, sexy bod, adding muscle mass increases your resting metabolism — meaning you'll burn more calories when you’re at home on your couch, enjoying a good Netflix binge. If you’re not looking to add any noticeable muscle, you can theoretically strength train twice a week and make use of that third day for cardio, but we wouldn’t recommend skipping it altogether.

You can strength train in a variety of ways, too. Lifting is an obvious option, but for those who are really looking for a leaner physique or who just hate lifting, pilates and intense vinyasa yoga are also fabulous. Functional training, like rock climbing or rowing, also qualifies.

Make sure to take a break between your strength training days. Most experts say that you need at least 48 hours for your muscles to recover. In the meantime, there’s cardio!

Cardio: 2-3 Days

Cardio is undoubtedly important, not only for keeping your heart healthy, but also for burning fat. Without getting too technical, you should aim to hit 85-100 percent of your target heart rate for roughly 15 minutes. You can calculate your maximum heart rate by subtracting your age from 220. So, if you’re 27, your max heart rate would be 193, and 85 percent of that would be 164.

You can get there with high-intensity interval training, long-distance running, Zumba, cardio kickboxing — whatever floats your boat.

Active Rest: 2 Days

Finally, one of the most important parts of your workout plan: active rest. Two days of your week should be fully focused on letting your muscles rebuild through gentle stretching, walking, restorative yoga, or foam rolling. By completing these kinds of workouts twice a week, you’ll be staying active and building flexibility all while chilling out!

The Dangers of Over-Exercising

It’s important to take time off from your workouts if health is your overall goal. For one thing, over-exercising can lead to adrenal fatigue and other disorders, as exercise is literally added stress for your body. Your adrenal glands respond to exercise by releasing stress hormones like adrenaline and cortisol, and over time, not giving your adrenals a break can lead to tiredness, lethargy, and even thyroid problems.

And besides, it’s important to take a mental break from exercise. When you start to obsess about fitness, is when a healthy habit turns into something more sinister. Do yourself a favor and take at least two days a week for rest or active recovery. Your body will thank you!
