Light Weight: Research Reports Brief Strength Training May Still Get Big Results

As an older adult, there are so many reasons you should regularly do strength training (also known as resistance training). Whether at the gym, walking outside, or even inside your home, using either body movements or equipment like dumbbells or resistance bands, regularly engaging your muscles is going to help keep you strong and mobile, undergirding your desire to be active and engaged in the world around you. Moreover, research studies also report that strength training is not only important to build and maintain strength, but it also plays a role in the reduction of visceral fat and support of cardiac health, not to mention the mood improvements (and cognitive support) that strength training can provide.

But is the trade-off for these benefits exhaustive hours of curling your arms with weights or squatting your legs indefinitely? New research seems to suggest that how long you engage in strength training may not be determinative of the positive outcomes you can achieve. In a brand new study published in PLOS One, researchers from Penn State report that even engaging in strength training for as little as 4 minutes per day can nonetheless significantly improve the physical functioning and mobility of older adults. According to this research, which involved 97 participants (average age of 74) who were randomized into 2 groups, one participating in 4 minutes of daily strength training and the other just undergoing their usual daily routines, after 12 weeks, those engaged in the short daily strength training regimen had measurable and meaningful improvements in their physical functioning and mobility. What exactly did they do for those four minutes each day? They engaged in 4 strength-building exercises, for 30 seconds each, with 30-second breaks in between, doing the following: push-ups, sit-to-stand from a chair, 2-armed rows, and stair stepping. For those who needed a bit of extra help, exercises were initially modified to be easier, and as participants progressed, they were urged to push themselves more. What was also impressive about this routine was that 81% of the participants were able to stick to the plan for the entire study. Having a strategy that is easy to undertake is half the battle when it comes to older adults and exercise (it’s been said that the majority of older adults do not follow the recommended guidelines of 150 minutes of strength training per week). So, with the results of this study, it appears that less than 30 minutes a week just might get you the strength you need to engage in an active life. As one researcher stated, “Exercise is the key to freedom.” So grab a resistance band and read more here.  

Other recent studies and analyses also point to a less-is-more (or “almost as good”) strategy for strength training. A recent post in Very Well Health argued that even one day of strength training a week can build and preserve strength, as long as the day utilizes both upper and lower body muscles. Harvard Health also recently published a post suggesting that the strength training strategy of two dumbbells, 3 exercises, and just 10 minutes can give you the full-body regimen you need to stay strong. Focusing on the concept of low-volume HIIT, with a few intensely performed exercises, you can work all your major muscle groups in a short period of time. However, you are advised to develop this short routine with a personal trainer to ensure that your form and lifting techniques are correct and will protect you from injury. You may also want to investigate an easy strength training regimen only using resistance bands, recently published in The Washington Post. With just a resistance band, a chair, and a wall, you’ll be able to practice and strengthen key body movements necessary for everyday life in the privacy of your own home. Strength training with minimal stress! So put a chair in place, and watch here.

Finally, do you still doubt that even at your age and with shorter regimens, building muscle and engaging in strength training is beyond your abilities? You may want to consider the story of Toril Moe, a 75-year-old Norwegian woman who has taken it upon herself to train other older adults (from ages 62-88) in strength training exercises. With a can-do attitude and her personal example of feeling 20 years younger than she technically is, Moe sets the bar for what can be accomplished and how you can be energized and strong if you commit yourself, regardless of your age.
