Lower-Body Kettlebell Workout for Strength | 12Reps App

By Will Duru, BSc (Hons) Sport and Exercise Science, Award-winning Personal Trainer with over 10 years of experience in strength training and optimising recovery.

As a personal trainer with more than a decade of experience helping people get stronger and healthier. Today, I want to talk about one of my favourite tools for building a powerful lower body, especially when you don’t have much time: the kettlebell.

If you want to build strong legs, firm glutes, and a solid core, you don’t need a gym full of complicated machines. In this article, I’ll show you a simple but incredibly effective lower-body workout using just one kettlebell. We’ll also cover why kettlebells are so good for your lower body and how to use the 12Reps app to keep making progress.

Why Use a Kettlebell for Your Lower Body and Core?

As a trainer, I love kettlebells because they are amazing for functional strength. This means they help you build strength that you can use in your everyday life. The unique shape of the kettlebell, with its offset center of gravity, challenges your muscles in a way that dumbbells and barbells don’t.

When you perform lower-body exercises with a kettlebell, you’re not just working your legs. Your core has to work extra hard to keep you stable. A study in the North American Journal of Sports Physical Therapy highlighted that kettlebell movements, especially swings, activate the muscles in the lower extremities, the core, and even the upper body all at once [1]. This makes your workouts incredibly efficient.

The swinging and lifting motions you do with a kettlebell also require your muscles to both generate power and control the weight. This eccentric (or decelerating) phase of the movement is fantastic for building stronger, more resilient muscles and connective tissues [1]. This is why kettlebells are so effective for building a strong foundation and reducing the risk of injury.

How I Use Kettlebells for Lower-Body Training

I introduce kettlebells to my clients to teach them how to generate power from their hips and connect their lower body to their core. Exercises like kettlebell swings and goblet squats are staples in my clients’ programs because they build a rock-solid foundation.

For the lower body, kettlebells are perfect for targeting the glutes, hamstrings, and quads. Because you can easily hold the kettlebell in different positions (in front of your chest, by your side, or between your legs), you can change the focus of the exercise to target different muscles. This versatility is key to creating a well-rounded lower-body routine.

Making Progress: My View on Progressive Overload

To keep getting stronger, you need to challenge your muscles. This is a principle I stress with all my clients, and it’s called progressive overload. It just means you have to gradually make your workouts harder over time.

With this program, you can apply progressive overload in a few simple ways:

  • Use a heavier kettlebell: Once you can complete all the reps and sets with good form, it’s time to move up in weight.
  • Do more reps: Try to add one or two more reps to each set.
  • Rest less: Cut your rest time between sets from 60 seconds to 45 seconds to make the workout more intense.

The 12Reps app is perfect for this. It lets you track and log your workouts, including the weights, reps, and sets you do. This makes it easy to see when you’re ready to increase the challenge and ensure you’re always moving forward.

Nutrition for Muscle Recovery and Growth

Working out is just one part of the equation. To recover properly and build muscle, you need to fuel your body with the right nutrients. Protein is key for repairing the muscle tissue that gets broken down during exercise.

So, how much do you need? For people who are active and doing strength training, research suggests aiming for 1.6 to 2.2 grams of protein per kilogram of body weight (that’s about 0.7 to 1.0 grams per pound) [2]. You should spread this intake out over at least four meals throughout the day.

Focus on lean protein sources like chicken, fish, eggs, and Greek yogurt. Also, don’t forget about complex carbohydrates (like oats, brown rice, and sweet potatoes) and healthy fats (like avocado, nuts, and olive oil). Carbs will replenish your energy stores, and healthy fats are important for overall health and hormone function, which aids in recovery.
