Combatting tricep jiggle doesn’t have to be a daunting task. In fact, a few simple bed exercises could be your secret weapon against that stubborn arm flab.
As we age, our bodies undergo a series of natural changes, including the loss of skin elasticity, a slowing metabolism, and a decline in lean muscle mass. These shifts, combined with hormonal changes, often lead to the accumulation of excess fat in the tricep area. While these factors might seem discouraging, there’s good news: you can address these concerns with some targeted exercises that are more effective than traditional weight training, especially once you hit 50.
The wellness experts at Dorado Maroma Spa highlight that even before reaching the big 5-0, subtle changes in our arms become noticeable. Their team of body-care specialists explains, “Arm jiggle in midlife isn’t usually due to a single cause. Instead, it’s the result of various age-related changes occurring simultaneously. As we enter our 40s, we begin to experience sarcopenia—a gradual loss of muscle mass—unless we’re actively working to maintain our strength.”
The triceps, in particular, are susceptible to weakening because they aren’t heavily engaged in most daily activities. While we may push shopping carts or carry handbags, these actions rarely provide the necessary challenge to strengthen the back of the arms effectively. By incorporating specific bed exercises into your routine, you can tackle arm jiggle more efficiently and regain confidence in your triceps.
“The reality is, ‘arm jiggle’ in midlife usually isn’t caused by just one thing. It’s typically a combination of very normal, age-related changes happening at the same time. After our 40s, we gradually begin to lose muscle mass, a process known as sarcopenia—especially if we’re not actively maintaining strength,” Dorado Maroma Spa’s body-care specialists share. “The triceps tend to weaken quickly because they aren’t heavily used in everyday movement. We push grocery carts and lift handbags, but we rarely truly challenge the back of the arms.”
