A NOT-SO-FUN FACT: Muscle power—the ability to produce force quickly—tends to decline faster than muscle strength in your 50s. And this explosive power is key to preserving your mobility and bone strength for the long haul, physiologists say. Consider these power fitness tips from Shari Andrews, physician, personal trainer and author of Find Your Pulse. (And share any questions with your health care provider.)

Get low. For a lower-body boost, try sit-to-stand drills, Andrews suggests. Move from a seated chair position to standing, back to seated—without using your hands to propel you. Or try bodyweight squats.

Move your upper body. Try torso moves like a standing side toss: Stand perpendicular to a wall with an inflatable ball at the hip that’s farther from the wall, then twist as you throw the ball against a wall.

Keep rests brief. When you’re focused on functional power training, resting just 30 to 60 seconds between sets will “keep [your] heart rate up and mimic real-world demands,” Andrews notes.

Focus on form. To avoid injuring yourself, master any movements before adding more weight or speed, Andrews says.

Squeeze in your sessions. “You don’t need a lot of time,” says Andrews, noting you can focus on building power two or three times per week. —Leslie Quander Wooldridge

WE ASKED EXPERTS how to shine on LinkedIn when you’re job hunting.

Make a splash. Focus on three items: your timeline photo, which should hint at your line of work; your headshot, which should be a recent, shoulders-up pic; and your headline, which should be zingy. Visit the LinkedIn Talent Blog for examples.

Summarize smartly. Write your LinkedIn summary in the first person, not third person, to sound more engaging. Use keywords that match the opportunities you’re seeking.

Remove unnecessary items. Prune your education and experience sections periodically to keep the focus on your current expertise and goals.

Highlight your talents. Weave relevant skills throughout your profile by including them in your summary and job descriptions as well as in the Skills section of your profile.

Focus on impact. Throughout your profile, emphasize the effect your work has had, spotlighting the numbers in any measurable results.

Give props. Share and request recommendations from colleagues to keep your profile fresh. —Gwen Moran
