How Many Exercises Per Workout? The Science-Backed Figures for Your Goals

It’s one of the most common questions you’ll hear in the gym: "Am I doing enough? Or am I doing too much?"

You see one person crushing 10 different exercises in an hour, while a powerlifter next to them does one exercise for the entire hour. Both seem to be getting results.

So, what’s the magic number? How many exercises should you actually do per workout?

If you’re looking for a single, simple answer, you'll be disappointed. There isn't one. But don't click away—what we have is something far better.

The "magic number" doesn't exist because the real answer depends entirely on your goals, your experience, and your training split.

This guide will replace your confusion with a clear, science-backed plan.

🧠 The Core Concept: Stop Counting Exercises, Start Counting Sets

 

First, let's shift your thinking. The fitness industry is moving away from "number of exercises" and focusing on a much more accurate metric: Total Weekly Volume.

• Total Weekly Volume

• The total number of hard sets you perform for a specific muscle group, added up over the entire week.

A "hard set" is one where you train close to failure (typically leaving only 1-3 reps "in the tank").

Why is this the better metric? Because 10 sets of one exercise is vastly different from 1 set of 10 exercises. Volume is what drives growth.

The Figure: Scientific consensus, including a 2017 meta-analysis, shows that 10-20 hard sets per muscle group per week is the optimal range for maximizing muscle growth (hypertrophy).

The number of exercises you choose is simply how you distribute that weekly volume.

• 12 weekly sets for your chest could be:

  • Workout 1: 3 exercises, 4 sets each.

  • Workout 1: 4 exercises, 3 sets each.

  • Workouts 1 & 2: 2 exercises of 3 sets in each workout (totaling 12 sets).

See? The number of exercises is flexible. It’s a tool to achieve your target volume.

🎯 How Many Exercises? The Answer Based on Your Primary Goal

 

With volume in mind, we can now provide the figures for how many exercises to perform. Your goal is the single most important factor.

 

1. For Hypertrophy (Building Muscle Size)

 

This goal loves variety. Hitting a muscle from different angles and with different movement patterns helps recruit a wider range of muscle fibers.

• Figure: Aim for 2-4 exercises per muscle group during its dedicated workout.

• Rep Range: 6-12 reps per set.

• Weekly Sets: 10-20+ per muscle group.

• Example "Chest Day":

  • Barbell Bench Press (3-4 sets)

  • Incline Dumbbell Press (3-4 sets)

  • Cable Crossovers (2-3 sets)

  • Total: 3 exercises, 9-11 total sets.

 

2. For Maximal Strength (Getting Stronger)

 

This goal is all about specificity and neural adaptation. It's less about variety and more about mastering a few key lifts.

• Figure: Focus on 1-3 primary compound exercises per workout.

• Rep Range: 1-5 reps per set.

• Weekly Sets: Volume is often lower, but intensity (the weight) is much higher.

• Example "Strength Day":

  • Barbell Squat (4-5 sets)

  • Bench Press (4-5 sets)

  • Pendlay Row (3-4 sets)

  • Total: 3 exercises. You might add 1-2 small "accessory" exercises (like tricep pushdowns) at the end, but the main work is done.

 

3. For Muscular Endurance

 

This goal is about training your muscles to resist fatigue. This is often done with lighter weights for more reps, or in a circuit style.

• Figure: Can be 4-6+ exercises per workout.

• Rep Range: 13-20+ reps per set.

• Weekly Sets: Often structured by time or in circuits rather than traditional sets.

• Example "Endurance Circuit":

  • Kettlebell Swings

  • Push-ups

  • Walking Lunges

  • Plank

  • Battle Ropes

  • Total: 5 exercises, performed back-to-back for 3-5 rounds.

 

4. For General Health & Fitness

 

Your goal is to be active, healthy, and strong for daily life, as recommended by groups like the NHS and ACE.

• Figure: Aim for 1 exercise for every major movement pattern or muscle group.

• Guideline: Hit all major muscle groups (legs, hips, back, abdomen, chest, shoulders, arms) at least twice a week.

• Example "General Health Workout":

  • Goblet Squat (Legs)

  • Dumbbell Row (Back/Pull)

  • Push-up (Chest/Push)

  • Overhead Press (Shoulders)

  • Plank (Core)

  • Total: 5 exercises.

🗓️ How Your Workout Split Changes the Numbers

 

Your training split (how you organize your week) is the final piece of the puzzle. Here’s how to apply the numbers.

Training Split	Frequency	How Many Exercises Per Workout?	E-E-A-T Explanation
Full-Body Workout	2-3 days/week	5-8 exercises total	This is the most authoritative recommendation for beginners. You do 1 exercise per major muscle group (e.g., 1 chest, 1 back, 1 quad, 1 hamstring, 1 shoulder).
Upper/Lower Split	4 days/week	6-10 exercises total	You have more time to focus. You might do 2-3 exercises for your big muscle groups (like chest, back, quads) and 1-2 for smaller ones (like biceps, triceps).
Body-Part ("Bro") Split	5-6 days/week	4-6 exercises total	On "Chest Day," you can dedicate your entire workout's volume to that one area. This means 3-5 different exercises all focused just on the pecs.

⚠️ The Big Mistake: "Junk Volume"

 

This is a key concept. More is not always better.

Junk Volume is any training you do after you’ve already triggered an optimal growth response. At this point, you’re not stimulating more muscle; you’re just adding fatigue, increasing your injury risk, and slowing down your recovery.

If you’re a beginner, your "effective sets" limit is low. Maybe 4-6 hard sets for a muscle group in a workout is all you need. For an advanced lifter, it might be 8-10.

The Figure: If your workout plan calls for 7 different chest exercises, you are almost certainly doing junk volume. For most people, 3-5 exercises per muscle group is the absolute maximum you should ever need in a single session.

Remember: The goal is to stimulate, not annihilate.

Your Blueprint: How to Find Your Number

 

Here is your step-by-step plan:

1. Pick Your Goal: Are you training for size (Hypertrophy), strength, or general health?

2. Pick Your Weekly Volume: Start at the low end. Aim for 10 hard sets per muscle group per week.

3. Pick Your Split: As a beginner, we recommend a Full-Body split, 3x per week.

4. Do the Math:

   • Goal: 10 sets for "Chest" per week.

   • Split: 3 full-body workouts.

   • Plan: Do ~3-4 sets for a chest exercise in each workout. (3 workouts x 3-4 sets = 9-12 total weekly sets).

   • Answer: You will do one chest exercise in each of your 3 weekly workouts.

As you get more advanced, you can add more volume (maybe 15 weekly sets) and move to an Upper/Lower split.

• Goal: 15 sets for "Chest" per week.

• Split: 2 upper-body workouts.

• Plan: Do 7-8 sets for your chest in each workout.

• Answer: You could do two chest exercises for 4 sets each, or three chest exercises for 3, 3, and 2 sets.

 

The Final Word

 

There is no single magic number of exercises per workout. The most effective approach is to focus on your total weekly volume (10-20 hard sets per muscle group) and then use exercises as a tool to achieve that volume based on your goals and schedule.

For most people, most of the time, a total workout will consist of 4-8 exercises.

• Beginners: Start with 3-5 exercises in a full-body routine.

• Intermediate/Advanced: Aim for 2-4 exercises per muscle group you're training that day.
