• Do Women Have to Lift Heavy?

  Do women have to lift heavy to see results? Will we get the same results from lifting light weights? In today's episode we dive into the science behind lifting weights and how age and hormones play a factor in the type of strength training we should be doing. After age 35, we naturally lose muscle unless we actively train to keep it. Less muscle = slower metabolism. That’s why strength training is non-negotiable! Declining Estrogen & Progesterone – Estrogen helps with muscle recovery. As levels decline, recovery slows.  Lower Testosterone – Testosterone is essential for muscle-building. As it decreases, it’s harder to maintain muscle. This is why lifting heavy won’t necessarily make you bulky (with good exercise selection)! Fluctuating Cortisol – Higher stress = higher cortisol, which can lead to muscle breakdown and fat storage. Managing stress and including low-intensity steady-state cardio (like walking) helps keep cortisol in check. Research confirms that Lifting light with high reps (at 30% of your one-rep max) is just as effective as lifting heavier with lower reps (at 70-80% of your one-rep max).

• How Much Protein Do You Really Need after 35?

  Why is protein so important after 35? As we age, our bodies become less efficient at building and repairing muscle, making protein intake essential for maintaining strength, metabolism, and overall health. But how much do we really need, and how can we fit it into busy schedules? In this episode, we sit down with Stephanie, our registered dietitian, to break it all down. She explains: The ideal amount of daily protein intake Myths about protein and weight gain Simple strategies to incorporate high-quality protein into meals—no supplements required From animal-based options like chicken and eggs to plant-based choices like lentils and tofu, there are plenty of ways to get enough protein without overcomplicating things. We also dive into the importance of protein timing, especially around workouts, and why consistency matters more than hitting an exact number every day. Whether you're trying to maintain muscle, support fat loss, or just feel more energized, this episode is packed with practical, science-backed tips to make protein work for you.

• How Should I Strength Train over 40?

  Strength Training is a Game-Changer! Essential for women over 40 to combat muscle loss, slower metabolism, and reduced bone density. It’s not only about aesthetics! Sweat and Soreness Are Misleading: Neither is an indicator of a good workout; focus on effective reps and structured progress instead. Heavy vs. Light Weights: Both can be effective if you reach “effective reps”—the point where the last reps are challenging but doable. Muscle Confusion Done Right: Occasional variation is great; too much change can lead to inflammation, fatigue, and central nervous system (CNS) overload. The 5 major components in creating an effective strength routine: Consistency trumps perfection! How to use Progressive Overload. Aim for 5–10 sets per muscle group weekly Walking helps accelerate fat loss, filling in the gaps strength training alone can’t cover.

• Strength or Walking—Which Should You Prioritize When Time is Tight?

  Strength or Walking—Which Should You Prioritize When Time is Tight? Research shows that both strength training and aerobic exercise (like walking) offer major benefits—but if you’re short on time, which one should you prioritize? In this episode, we break down two key studies and share expert insights to help you make the best choice. Strength training boosts metabolism, preserves muscle, and transforms your body composition—especially for women over 35. Walking helps accelerate fat loss, filling in the gaps strength training alone can’t cover. Plus, we discuss why your fitness watch might be misleading you when it comes to calorie burn! The best approach combines both, but when you’re in a crunch, knowing what to focus on is key. Tune in to find out what works best for you! 7–Day Free Trial!

• Do I Need Creatine or Protein Supplements? Let's ask the R.D.

  Social media is flooded with claims that the only way to really make progress in our workouts is to supplement with creatine, protein, and other products. I asked Stephanie, our registered dietitian, to give us the science behind these claims. What she says might surprise you! Roughly half of our daily creatine is produced by our body, and the other half typically comes from read meat, poultry and fish. Who benefits from a creatine supplement? Protein is stored in the body differently than carbs and fat – there’s no reserve that can be tapped into directly. This is why dietary intake of protein is essential. If I’m in my 40’s and I’m strength training, do I need a protein supplement?   Get a 7–day FREE trial to my fitness studio studio.momsintofitness.com   Download the App iOS Google Play   Follow Lindsay on Instagram @lindsaybrinfitness Follow Lindsay on YouTube @lindsaybrinfitness
