As you age, it’s common to lose muscle mass, collagen, and skin elasticity—all of which can contribute to under-arm flab. The good news? The right strengthening workouts can sculpt lean muscle underneath, helping to support a firmer appearance when combined with other healthy lifestyle habits.

“Strength training can rebuild the muscle underneath and improve the arm’s shape, but it cannot completely tighten loose skin or selectively remove arm fat. That part is important to be honest about. The best approach is building muscle, maintaining a healthy overall body-fat level, eating enough protein, and giving the process time,” explains Jacob Siwicki, founder and head coach of Siwicki Fitness, NCSF and AFAA certified, former top 1% globally ranked Equinox group fitness instructor (2019), Dartmouth economics graduate and former Dartmouth football player, fitness expert on FOX 5 DC, ranked #1 personal trainer in D.C. in 2021.

In addition, toning your arms isn’t just about aesthetics. Strong arms make daily tasks like picking up grocery bags, carrying your grandchildren, and even swinging a golf club or pickleball paddle easier.6254a4d1642c605c54bf1cab17d50f1e
