Many beginners and even experienced gym goers don’t exactly know “How Many Exercises per Muscle Group Should You Do?“
Designing an effective workout routine involves understanding various factors, including exercise selection, volume, intensity, and frequency.
Among these, determining the appropriate number of exercises per muscle group is crucial for maximizing muscle growth and overall fitness gains.
While individual differences and goals play a role, research offers insights into optimal exercise prescription.
Understanding Exercise Volume
Exercise volume refers to the total amount of work performed during a workout, typically quantified by sets, reps, and load. Balancing volume is essential to prevent overtraining while stimulating muscle adaptation.
For each muscle group, the volume should be sufficient to induce hypertrophy without causing excessive fatigue or injury.
Research-Based Recommendations
Several studies provide guidance on the number of exercises per muscle group:
1. American College of Sports Medicine (ACSM)
ACSM recommends performing 8-10 exercises targeting major muscle groups, including chest, back, shoulders, arms, legs, and core, in a comprehensive resistance training program.
However, they emphasize the importance of individualization based on fitness level, goals, and time availability.
2. National Strength and Conditioning Association (NSCA)
NSCA suggests including 1-2 exercises per major muscle group in a resistance training routine. This approach ensures adequate stimulation of muscle fibres while allowing for recovery and progression.
3. Meta-Analyses:
Meta-analyses examining resistance training variables indicate that performing 2-4 exercises per muscle group is associated with significant muscle hypertrophy and strength gains.
This moderate volume approach optimizes training efficiency while promoting muscular adaptation.
| Do you know?According to James Krieger’s 2010 meta-analysis, increasing the number of sets performed per exercise boosted muscle growth. |
Muscle-Specific Studies
Research focusing on individual muscle groups suggests variability in optimal exercise volume.
For example, larger muscle groups like the quadriceps and back may benefit from 3-4 exercises, while smaller muscles such as the biceps and triceps may require 1-2 exercises for sufficient stimulation.
Individual Considerations
While research offers general guidelines, individual factors must be considered when determining exercise volume:
1. Training Experience
Novice lifters may require fewer exercises initially to adapt to resistance training, while advanced lifters may benefit from higher exercise volumes to continue making progress.
2. Recovery Capacity
Factors such as age, sleep quality, nutrition, and stress influence an individual’s ability to recover from exercise. Adjusting exercise volume based on recovery capacity prevents overtraining and supports long-term progress.
3. Goals
Individuals aiming for muscle hypertrophy may prioritize higher exercise volumes, while those focusing on strength development may emphasize heavier loads and lower rep ranges.

Conclusion
Determining the optimal number of exercises per muscle group involves balancing scientific evidence with individual considerations.
While general recommendations exist, such as 2-4 exercises per muscle group, customization based on factors like training experience, recovery capacity, and specific goals is essential.
By applying research-backed principles and individualizing exercise prescriptions, individuals can design effective workout routines to maximize muscle growth and overall fitness gains.
