Are you trying to tone your arms after 50? One expert claims to know the secret. Kristine Rucker, aka The Arm Coach, is a fitness coach and influencer specializing in helping people tone their arms. In a new post, she reveals the one secret you need to learn if you want strong arms. "The real reason you're not getting the arms you want…and it's NOT your workouts," she says.

​She Thought Her Workouts Were the Problem

"For the longest time, I thought my workouts were the problem. Maybe I wasn't lifting heavy enough. Maybe I wasn't doing the right exercises. Maybe I needed more reps, different movements, a better routine," she says in the post.

​It Was Actually Her Mindset

"So, I kept searching for the perfect plan. But no matter what I tried, my arms didn't change the way I wanted them to," she says. "And then I realized—it wasn't my workouts holding me back. It was my mindset."

​She Stuck in an "All-Or-Nothing" Cycle

"I was stuck in an all-or-nothing cycle. Some days, I was on fire, pushing myself hard, eating 'perfectly.' Other days, I'd fall off track and think, Oh well, I already messed up. Might as well start over Monday. Sound familiar?" she says.

​You Need to Stay Consistent

Here's the truth: "It's not your workouts," she says. "It's your ability to stay consistent. And that consistency doesn't come from forcing yourself—it comes from loving self-discipline."

​And Guide Yourself with Care

"Loving self-discipline isn't about being strict—it's about guiding yourself with care. It's about making choices that feel good in the long run, not just in the moment. It's what keeps you going, even when motivation fades," she says.

​Everything Changed When She Stopped Fighting Herself

"When I stopped fighting myself and started practicing gentle, loving discipline, everything changed. My workouts finally worked—not because they were different, but because I was different," she says.

​Tracking Is Also Important

In another post, she reveals another tactic that helps tone arms: Tracking. "Why tracking is the fastest way to toned arms: Because what you measure, you improve," she says.

​She Used to Wing It

"I used to wing it—showing up to workouts, hoping for progress, but never really knowing if I was getting stronger. And because I wasn't tracking anything, I'd get discouraged and quit before I ever saw real results," she said.

​Tracking Gave Her Proof, Kept Her Consistent, and Helped Her Focus on Progress

Then she started writing things down. "Tracking gave me proof. I wasn't guessing anymore—I could see my strength improving week by week," she says. "It kept me consistent. Seeing my progress in front of me made it easier to keep going. It helped me focus on progress, not perfection. Instead of obsessing over the mirror, I focused on how much stronger I was getting," she continued.
