When it comes to strength training, one size does not fit all. The number of days you should train each week and the structure of your sets, reps, and overall volume depends largely on your goals—whether you’re aiming for hypertrophy, strength, or endurance. In this article, we’ll break down how many days per week you should be hitting the weights and the ideal number of sets, reps, and volume for each goal, all backed by scientific research.
Understanding Training Frequency: How Many Days Should You Train?
Training frequency refers to how often you train a particular muscle group each week. Depending on your goals, you may need to train more or less frequently.
- Hypertrophy (Muscle Growth). If your primary goal is to increase muscle size, research suggests training each muscle group 2-3 times per week is optimal. A study published in Sports Medicine found that training frequency significantly impacts muscle hypertrophy, with a higher frequency promoting greater muscle growth . Training twice a week allows for adequate recovery while still providing enough stimulus for growth.
- Strength. Gains are best achieved with a lower frequency but higher intensity when looking to increase strength. Training each muscle group 1-2 times per week is usually sufficient. A study in the Journal of Strength and Conditioning Research found that training frequency had less impact on strength gains than volume and intensity. Therefore, focusing on fewer sessions with higher weights is ideal.
- Endurance. For muscular endurance, higher frequency training may be beneficial. Training a muscle group 3-4 times per week can help build the stamina needed for prolonged activities. However, the intensity should be lower, with lighter weights and higher reps to avoid overtraining.
Determining Sets, Reps, and Volume Based on Goals
Once you’ve determined how many days you should train based on your goals, the next step is to structure your workouts with the right sets, repetitions, and volume.
- Hypertrophy (Muscle Growth)
- Sets: 3-4 sets per exercise.
- Reps: 8-12 reps per set.
- Volume: 60-120 reps per muscle group per week.
- Strength
- Sets: 3-5 sets per exercise.
- Reps: 3-6 reps per set.
- Volume: 30-60 reps per muscle group per week.
- Endurance
- Sets: 2-3 sets per exercise.Reps: 15-20 reps per set.Volume: 90-150 reps per muscle group per week.
Weekly Training Programs Based on Goals
Let’s take a look at how you might structure your weekly training program based on your goals.
- Hypertrophy
- Frequency: 4-5 days per week.
- Split: Push/Pull/Legs/Upper/Lower.
- Example:
- Monday: Push (Chest, Shoulders, Triceps)
- Tuesday: Pull (Back, Biceps)
- Wednesday: Legs (Quads, Hamstrings, Glutes)
- Thursday: Upper Body (Chest, Back)
- Friday: Lower Body (Legs, Core)
- Saturday/Sunday: Rest
- Strength
- Frequency: 3-4 days per week.
- Split: Full-body or Upper/Lower.
- Example:
- Monday: Full Body (Squats, Bench Press, Deadlift)
- Wednesday: Full Body (Overhead Press, Rows, Lunges)
- Friday: Full Body (Deadlift, Pull-Ups, Dips)
- Saturday/Sunday: Rest
- Endurance
- Frequency: 5-6 days per week.Split: Full-body or Circuit Training.Example:
- Monday: Full Body (Circuit 1)Tuesday: Full Body (Circuit 2)Wednesday: Active Recovery (Low-Intensity Cardio)Thursday: Full Body (Circuit 3)Friday: Full Body (Circuit 4)Saturday: Full Body (Circuit 5)Sunday: Rest
- Frequency: 5-6 days per week.Split: Full-body or Circuit Training.Example:
Conclusion
The optimal number of strength training days, sets, reps, and volume depends largely on your individual goals. Whether you’re aiming for hypertrophy, strength, or endurance, tailoring your training program to these variables can help you achieve the best results. By following the guidelines laid out here, you can create a weekly training program that aligns with your objectives, all backed by scientific research.
For those looking to get the most out of their strength training, it’s essential to not only consider the frequency but also the structure of each workout. By understanding the relationship between sets, reps, and volume, you can craft a routine that maximizes your gains, regardless of your goal.
