Strength training is a fundamental aspect of maintaining a healthy lifestyle, often regarded as one of the most effective biohacks for longevity and overall well-being. Whether you’re just starting your fitness journey or are a seasoned athlete, understanding how much strength training you need to see results is crucial. This article will explore the recommended frequency and intensity of strength training based on your fitness level and goals.

Understanding the basics of strength training

According to the Centers for Disease Control and Prevention, adults should engage in muscle-strengthening activities at least twice a week to promote overall health. However, even a single session of resistance training per week can yield benefits for beginners, as highlighted in a recent study published in BMC Sports Science, Medicine and Rehabilitation.


How much strength training do you need?

Experts suggest that the amount of strength training you need varies based on your experience level and fitness goals. Here’s a breakdown:

1. Beginners aiming to build muscle: If you’re new to strength training, it’s recommended to start with two to three nonconsecutive sessions per week. This frequency helps establish a routine and provides the necessary stimulus for muscle growth while allowing adequate recovery time. Each session can be as short as 15 to 20 minutes initially, gradually increasing to 45-60 minutes as you build endurance.


For beginners, a full-body workout is ideal. You can perform one exercise per muscle group for three to five sets of five to eight repetitions. This approach not only builds strength but also ensures functional muscle growth.

2. Intermediate lifters looking to progress: If you already lift weights and want to continue progressing, aim for three strength training sessions per week. Each session should last between 30 to 60 minutes, focusing on progressive overload—gradually increasing the weight, sets, or repetitions over time. This method challenges your muscles, stimulates growth, and improves bone density.

3. Maintaining your gains: For those who have been strength training for a while, maintaining muscle mass becomes easier. If you’ve been training consistently, you may only need one full-body workout per week to maintain your gains. However, for optimal results, two to three sessions per week are still recommended.

4. Runners looking to prevent injuries: If you’re a runner, incorporating strength training at least twice a week is essential. One session should focus on foundational movements, while the other can target specific areas like core stability and hip strength. This balance not only enhances overall strength but also helps prevent injuries.

5. The bare minimum for bone and joint health: To protect your bones and joints, strength training at least twice a week is advisable. This frequency helps maintain muscle mass and bone density, which is crucial as we age. Full-body workouts and compound exercises like squats and deadlifts are effective for building functional strength.

Why regular strength training is essential

Regardless of your fitness goals, regular strength training offers numerous health benefits:

  • Prevents injuries and improves metabolic health.
  • Reduces the risk of cardiovascular diseases.
  • Supports bone density, particularly in women, helping to combat osteoporosis.
  • Enhances balance, mobility, and functional strength, which are vital for daily activities.

Strength training is an investment in your future health. It ensures that you maintain physical strength and resilience as you age, allowing you to live independently and actively.

Incorporating strength training into your routine is essential for achieving optimal health and longevity. Whether you’re a beginner or an experienced lifter, understanding how much and how often to train can help you reach your fitness goals effectively. Remember, consistency is key, and even small amounts of strength training can lead to significant health benefits.
