How Hard Should I Work Out?

When starting on a fitness journey, one of the most common questions I get asked is, “How hard should I work out?” The answer is part art and part science with the age-old answer of “it depends.” The right balance between intensity and recovery is crucial for achieving your fitness goals while minimizing the risk of injury. 

‍

Exercise intensity refers to how hard you are working during your workout. It can be measured in various ways, including heart rate, perceived exertion, and even the RIR method. RIR is a valuable tool that helps you gauge how many more repetitions you could perform before reaching failure. For example, if you could do two more push-ups after completing ten, you would have two repetitions in reserve. Using RIR can help tailor your workouts to your fitness level and goals. 

‍

Here’s a simple breakdown: - 0 RIR: You could not perform another repetition. This is maximal effort and is often not sustainable for most workouts. - 1-2 RIR: You have a couple of repetitions left in the tank. This intensity is often recommended for strength training and can yield significant gains without risking injury. - 3+ RIR: You could perform several more repetitions. This is often too easy for strength training but may be appropriate for endurance activities.

Universal Guidelines for Exercise in Adults According to the Centers for Disease Control and Prevention (CDC) and the American College of Sports Medicine (ACSM), adults should aim for the following universal exercise guidelines: 

1. Aerobic Activity: At least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity each week. 

2. Strength Training: Engage in muscle-strengthening activities on two or more days per week, targeting all major muscle groups. 

3. Flexibility and Balance: Incorporate stretching and balance exercises, especially for older adults, to enhance overall physical function. 

‍

These guidelines provide a solid framework for how hard you should work out. However, the key lies in listening to your body and adjusting your workouts as needed to promote long-term success.

When dealing with a nagging injury or discomfort, one of the most critical aspects to consider when determining workout intensity is tissue irritability. This term refers to how an individual responds to exercise, particularly in terms of pain or discomfort. If you experience increased pain or discomfort during or after a workout, it may be a sign that you need to reduce the intensity of your exercise. Here’s how to approach workout intensity when dealing with irritability in mind: 

‍

1. Listen to Your Body: Pain is a signal from your body in the event of a threat or perceived threat to the body. If you feel pain (beyond typical muscle soreness) during an exercise, modify the activity. It is not altogether necessary to completely stop the exercise. However, ignoring persistent pain can lead to more significant injuries down the road. 

2. Adjust Your RIR: If you’re experiencing discomfort, consider decreasing the intensity of your workout. Aim for a higher RIR—perhaps 3 or more—so that you’re not pushing your body too hard. This adjustment allows for recovery while still maintaining a good training stimulus that can still build strength. 

3. Incorporate Active Recovery: On days when you feel more discomfort, consider engaging in low-impact activities like walking, cycling, or swimming. These exercises can help promote blood flow and recovery without placing excessive strain on your body. 

4. Consult a Professional: If you frequently experience pain or discomfort during workouts, it’s wise to consult a physical therapist. We can help identify any underlying issues and develop a tailored exercise program that considers your individual needs.

Finding Your Balance The key to a successful fitness journey is finding the right balance between intensity and recovery. Here are some tips to help you determine how hard to work out: - Start Slow: If you’re new to exercise, begin with moderate intensity and gradually increase as your body adapts. You’ll be amazed at the way your body responds to movement! 

- Monitor Your Progress: Keep track of your workouts, noting your RIR and any discomfort. This information will help you make informed decisions about when to increase or decrease intensity. - Prioritize Recovery: Rest days, proper nutrition, and hydration are essential for long-term progress and injury prevention.

Determining how hard to work out is a personal journey that requires listening to your body, understanding your limits, and adjusting your intensity as needed. By incorporating the concept of repetitions in reserve, and considering your tissue irritability, you can create a balanced and effective fitness program. Remember, fitness is a lifelong journey—finding the right intensity level is key to enjoying the process and achieving your goals. Happy exercising!
