How many sets should you be lifting for muscle growth in older age? New study

There are plenty of reasons to try resistance training in your later years.

Even if you start lifting weights later in life, research continues to support the benefits. Committing to one year of heavy resistance training has been proven to provide benefits that can last for four years. People often say, “I’m too old for that,” but this mounting research is another reason we shouldn’t let age hold us back from swelling those muscles. Recently, researchers analyzed the effects of resistance training on people 65 years old and over. Let’s look at the study and the proven benefits of resistance training and picking up those dumbbells.

The study

Leg press machine.

In the review and meta-analysis published in Experimental Gerontology, researchers set out to explore the effects of resistance training on muscle hypertrophy in adults aged 65 and up. Muscle hypertrophy refers to an increase in muscle size. The researchers looked at changes in quadriceps muscle size, lean mass, and fiber area, and they considered factors like age, training volume, and training duration. 

The meta-analysis involved 32 randomized controlled trials. Participants engaged in training programs for 8-52 weeks, which usually involved performing exercises like the leg press and knee extensions two or three times every week. The researchers measured muscle fiber area, muscle cross-sectional area, and lean muscle mass.

The results

The results showed:

  • Resistance training greatly increased quad size and fiber area.
  • Performing 12 or fewer weekly sets per quad muscle was enough to yield hypertrophy or increase muscle size.
  • Training durations longer than 12 weeks were linked to greater hypertrophy in the type II muscle fibers.
  • Age didn’t drastically affect the response.

The takeaway

This new research shows us that you can increase the size of your muscles with resistance training later in life, so there’s no need to let age get in the way of bulking up and building strength and size. For those aged 65 plus, performing 12 weekly sets per muscle group and training two or three times every week is sufficient for muscle hypertrophy. While some senior lifters might still need some modifications and to focus on specific exercises and durations, other research also shows that around 10-20 sets per week is enough to grow your muscles.

If you’re not sure about your workout plan and how many sets you should do, you can check with a personal trainer or qualified practitioner.

The evidence-based benefits of resistance training

The evidence-based benefits of resistance training include:

  • Improving your cardiovascular health.
  • Improving blood pressure.
  • Improving cholesterol.
  • Enhancing your muscle strength and tone, which can reduce your risk of injury.
  • Sculpting your physique.
  • Boosting your metabolic health.
  • Boosting your cognitive function and brain power.
  • Perking up your mood.

There are plenty of reasons to reach for those dumbbells or kettlebells or make your way toward the gym machines.

Is single-set training enough to build muscle and strength? Researchers find out

Will powering through one set twice a week still generate results?

If you only have time to get in one single set, is it really worth it? Will you make gains over time with single-set training? Today, we lead busy lives and want to use our time wisely. That being said, we still want to see progress and level up our fitness when strength training. Researchers and fitness buffs are increasingly discussing the minimal effective dose for boosting muscle mass and strength. In a recent study, researchers wanted to find out if you can still build strength and muscle with single-set training. The results should encourage us to train smarter, not necessarily harder. We shouldn’t let a lack of time hold us back from making gains. 
The study 

In a new study on SportRχiv, researchers assessed how performing single-set resistance training to muscle failure compared with training with 2 reps left before failure. They wanted to see how these two different training methods affected muscle growth and strength and if low-volume training was beneficial for trained lifters.

Here’s how many days it took this runner to complete 7 marathons on 7 continents

From teeth-chattering temperatures to 100-degree weather and rough terrain; this runner from Texas still crossed the finish line.

Completing one marathon shows an impressive degree of strength, dedication, and athletic prowess. A full marathon is 26.2 miles, and in 2023, the average running time for men was 4 hours and 14 minutes. How long it takes you to cross that finish line depends on factors like your fitness level and age. Elite marathoners might take just over two hours, whereas others might take up to eight hours or longer. One runner decided to run seven marathons on seven continents, which is an interesting and challenging goal to set your mind on. 
7 marathons on 7 continents in 7 days 

Mike Rogers is a 71-year-old runner from Texas who’s part of the USA FIT Lubbock run club. While you might be picturing your typical marathon, Mike started this fitness challenge in teeth-chattering temperatures below freezing in Wolf’s Fang, Antarctica. Mike was one of 55 people who completed the Great World Race in November, covering seven marathons on all seven continents in seven days to help raise money for charities such as Make a Wish. Seven is the magic number when it comes to the Great World Race.
