Your Simple Guide to Progressive Overload Training

Building fitness starts with taking on new challenges. But if you just do the same old routine over and over again without ever increasing the difficulty, you’ll eventually plateau.

By gradually increasing how much you lift, how fast you work out and how long you push yourself, you’ll see a wide range of benefits and improvements to your overall strength. Sports medicine physician Dominic King, DO, explains the science behind progressive overload training and how you can safely do it at home or in the gym.

What is progressive overload?

Progressive overload is when you gradually increase the load or stress that’s placed on your muscles during strength training and workouts. This tightly controlled approach to training can build muscle mass and improve your strength and endurance over time.

“You can progressively overload your muscles with more weights, more repetitions and more sets,” explains Dr. King. “Or you can reduce the length of time you rest between exercises to put more stress on your muscles.”

Progressive overload workout plan

The key to progressive overload training is to change one factor at a time by increasing:

• The amount of weight you’re lifting
• The number of repetitions you do for each activity
• How long you work out
• How fast you train, or by shortening your rests between sets and reps

Just one of these changes to a single technique can challenge your muscles to work harder. Once that challenge becomes easier for you, pick another training variable to continue the progressive overload.

“Think of these decisions as different gears in a car,” says Dr. King. “If you stay in first gear at 7,000 RPMs, the engine will burn out — that’s why you shift gears.”

In general, progressive overloading should be used in a strength training routine that involves:

• Five to six different exercises that focus on both your upper and lower body
• Three sets of six to 15 reps for each activity

You can do these with machines or with free weights, like dumbbells. You can also use the concept in cardio-based activities, like running or jogging.

Here are four progressive overload workout plans for each approach:

1. Increase weight

By increasing the weight you lift, you add more direct stress so that you can build muscle and improve your strength. Dr. King recommends adding 5 pounds of weight to a lift if you feel like you could do at least five more repetitions on your last set.

For example:

• Week 1: Perform bicep curls with 5 pounds.
• Week 3: Perform bicep curls with 10 pounds.
• Week 5: Perform bicep curls with 15 pounds.

“Small adjustments might feel gradual, but depending on the workout, they can add up quickly,” Dr. King explains. “If you’re struggling to finish a set or experiencing pain, it’s a clear sign the weight is probably too heavy.”

2. Increase repetitions

As you increase the number of repetitions for a workout, focus on lifting and lowering your weights with a slow, controlled tempo. This puts the right amount of force on your muscles to improve endurance and strength.

In general, Dr. King suggests aiming for six to 15 reps for each exercise. When you can do 15 reps of any exercise with little-to-no difficulty, drop the number of reps back down and add more weight.

For any workout routine, changing your repetitions may look like this:

• Week 1: Perform three sets of six reps.
• Week 3: Perform three sets of 10 reps.
• Week 5: Perform three sets of 15 reps.
• Week 7: Perform three sets of six to 10 reps and add 5 pounds of weight.

3. Increase duration

Training for longer periods or shortening the rest time between sets pushes your muscles to boost endurance. When taking this approach to progressive overload, Dr. King advises to choose one of the following.

Work out for longer durations:

• Week 1: Train for 30 minutes.
• Week 2: Train for 45 minutes.
• Week 3: Train for 60 minutes.

Build in shorter rest periods:

• Week 1: Rest for 60 seconds between sets.
• Week 2: Rest for 45 seconds between sets.
• Week 3: Rest for 30 seconds between sets.

“Your body thrives on being challenged, but just as importantly, it needs rest to recover,” stresses Dr. King. “Limit shorter rest periods to brief phases, and build in a ‘deload’ week every four to six weeks. That’s when you either extend your rest time or lighten the weight to give your body the recovery it needs.”

4. Increase intensity

Sometimes, quickening your pace with lighter weights can provide an intensity boost. Be careful not to go so fast that you throw off your form, which can increase your risk of injury.

When strength training, try the following:

• Week 1: Perform six reps in 60 seconds.
• Week 3: Perform 10 reps in 60 seconds.
• Week 5: Perform 15 reps in 60 seconds.

When running, alternate between fast and slow intervals:

• Week 1: Run for 30 seconds, then walk for 60 seconds. Repeat 10 times.
• Week 3: Run for 45 seconds, then walk for 45 seconds. Repeat 12 times.
• Week 5: Run for 60 seconds, then walk for 30 seconds. Repeat 13 times.

Progressive overload benefits

With progressive overloading, you can:

• Target both small and large muscles
• Prevent plateaus and exercise boredom
• Achieve performance gains
• Strengthen your joints
• Boost energy levels
• Build endurance
• Increase muscle strength
• Improve recovery time

“No exercise works just a single muscle,” Dr. King emphasizes. “Progressive overload lets you challenge smaller muscles with more frequent training, while larger muscles can be pushed with heavier weight.”

Progressive overload risks

If you’re not focused on proper form and technique, or you push yourself too hard, you can run the risk of:

• Overuse injuries
• Tendinopathy
• Muscle strains
• Stress fractures

Older adults, especially those with heart issues and other conditions like osteopenia or osteoporosis, have a higher risk of injury and should work with a physical therapist or athletic trainer before trying progressive overload.

“Lifting too much too soon can overload your body and lead to significant pain,” warns Dr. King. “With progressive overload, avoid making too many changes at once. If you start to feel pain, scale back until you understand your limits.”
