client: Lauren | personal trainer: Francesca Pucher, co-owner, Fitness 121 | location: Roseland, New Jersey
In search of progress. Lauren was just 13 years old when she first met Francesca Pucher, personal trainer and co-owner of Fitness 121 in Roseland, New Jersey. Lauren’s mom was working with Pucher and asked for some advice on how to help her daughter with her ice skating. She wondered if Lauren’s performance would improve if she incorporated some strength training into her weekly routine.Read More
Over the years, experts have questioned the accuracy of body mass index scores, known as BMI “z-scores,” for estimating body fat percentages in kids (the z is specific to younger age groups and requires complicated calculations to get results). The criticism is that adolescent weight doesn’t scale with height, which can produce faulty data. Now, researchers claim to have discovered a new, more accurate formula for measuring body fat in kids aged 8–17.Read More
Researchers from Case Western University in Cleveland wanted to determine if providing gifts to new gym members would incite them to visit the gym on a regular basis. The scientists specifically chose new members, theorizing that this group’s motivation to go to the gym was high.Read More
To minimize their future immobility risk, older adults should cut television time and boost activity levels, says new research.
Scientists looked at data on 134,269 subjects aged 50–71 from six states over 8 years. The data included self-reported total sitting time, television viewing time and physical activity intensity, as well as health histories. At follow-up, study participants provided information on walking pace and mobility, indicating whether they were “unable to walk” or could keep up an “easy walking pace.”
Traditional foam rollers have become widespread in the fitness setting. Recently, some manufacturers have added vibration technology to their products. Does the added element provide any extra benefit? Researchers from California State University Dominguez Hills in Carson, California, the National Academy of Sports Medicine in Chandler, Arizona, and Nova Southeastern University in Fort Lauderdale, Florida, wanted to find out.Read More
Higher earners may have more resources to boost activity levels than lower-income people, but that doesn’t make the better-off less sedentary, says a recent study.
In this study, published in Preventive Medicine (2017; 103, 91–97), researchers compared the activity levels of subjects with an annual income of $20,000 to those of people making $75,000 per year or more. The 5,206 subjects wore accelerometers for a week. The main variables were household income and amount and intensity of physical activity. Here’s what the scientists found:
Exercise is known to cause a release of endorphins. New research suggests that some forms of exercise are more effective at triggering a flood of the happy hormones than others.
This small study included 22 recreationally active men aged 21–36 years who completed three different protocols on separate days: a 60-minute moderate-intensity aerobic session, a high-intensity interval training (HIIT) session and a period of rest. The men underwent positron emission tomography, which measures endorphin release. They also reported on their moods throughout the intervention.
PODCAST!: Rick Mayo, founder and CEO of North Point Fitness and Alloy Personal Training Solutions, found immediate and startling success as a young personal trainer in Atlanta, only to come close to losing it all. Instead of giving up, he learned from his misfortune and changed his strategy, which led to success on a global scale.

Research has shown that obesity can limit mobility in older adults. According to a new study published in Obesity (2017; 25 , 1199–1205), moderate-intensity exercise may help.
As part of the Lifestyle Interventions and Independence for Elders (LIFE) Study, 1,635 sedentary individuals aged 70–89 completed an exercise- or education-based intervention. The subjects ranged from nonobese (BMI?
Previous research has determined a link between metabolic syndrome and reduced muscular strength and resistance training levels. A new study aimed to determine if resistance exercise—with or without aerobic exercise—could offer protection against developing the disease.Read More
What does a 19-year-old have in common with a 60-year-old? Both achieve about the same amount of weekly activity, according to new research.
This information comes from a study of 12,529 individuals aged 6–85 who participated in the National Health and Nutrition Examination Survey. The researchers’ primary goal was to analyze lifetime physical activity (PA) changes via accelerometer data—and their conclusions are disheartening. Here are some key points from the report:
Stepping on the scale daily may help women lose weight, according to a
new study. For 2 years, at intervals, 294 college-age women provided information on their self-weighing practices and underwent body mass index and body fat testing. According to the data, women who weighed themselves daily saw significant decreases in BMI and body fat percentage over time.
A lifestyle change. When busy mom Caroline first met Los Angeles–based personal trainer Ara Keshishian, her goals were simple: She wanted to lose fat and build strength. She was eager and motivated and hoped to see fast results. The two agreed to a 1-month trial program, meeting 4–5 times per week early in the morning.Read More
A common characteristic among people with type 2 diabetes is dysfunction of beta cells, which are responsible for storing and releasing insulin. New research suggests that high-intensity training workouts may help to restore beta-cell function.Read More
You’re running along your favorite path and then it happens: You get a cramp in your hamstring. While theories abound, there is limited consensus on why exercise-associated muscle cramps (EAMC) develop and how to get rid of them. A research review from the Brooks College of Health at the University of North Florida may clear up the confusion.
The review, published in Muscle & Nerve (2016; 54, 177–85), featured a series of studies analyzing the etiology and treatment of EAMC. Here’s what they learned:
Access to indoor climbing gyms has become more widespread, and so, too, has interest in
the benefits of the sport. Recently, a team of researchers from the University of Arizona and the University of Erlangen-Nuremberg in Germany studied the impact of indoor climbing
