So, you’re hitting the pavement to get that perfect lift and shape. But can running really make your glutes bigger? Let’s break it down.

Running is fantastic for building aerobic endurance, and yes, it can also give a boost to your glutes – the powerhouse muscles that make up your backside. But whether running can actually make your butt look bigger? That depends on the type of running you’re doing.

Can Running Really Build Your Butt?

Running can definitely work your glutes, toning and strengthening them while helping you burn calories. However, building actual muscle size through running isn’t exactly the same as lifting weights.

Distance running and sprinting target your muscles differently, so let’s look at the two types of muscle fibers engaged by each:

  1. Type I (Slow-twitch fibers) – These are used in longer, endurance-based running like 5Ks or marathons. They keep you going for miles but aren’t as focused on muscle growth.
  2. Type II (Fast-twitch fibers) – These are used in high-intensity, short bursts like sprints, which build a more muscular look in the glutes.

Distance Running and Your Glutes

If you’ve noticed that distance runners often have lean, toned legs rather than a more defined backside, there’s a scientific reason for it. Endurance running primarily activates those Type I, slow-twitch muscle fibers. These fibers are smaller and get plenty of oxygen from your blood flow, which keeps you moving for longer stretches.

So, while endurance running will tone your glutes and keep them strong, you likely won’t see a dramatic increase in size. But don’t worry – even though it won’t give you a bigger booty, distance running still strengthens your glutes and enhances overall muscle tone.

Want a Bigger, Stronger Butt? Sprint It Out!

For those wanting a rounder, more muscular backside, sprints are where it’s at. Sprinting uses Type II, fast-twitch fibers that activate during quick, powerful movements. Unlike Type I fibers, Type II don’t rely on oxygen, meaning they can support short, intense bursts of energy – perfect for building muscle.

These fast-twitch fibers respond better to growth, making sprints an ideal anaerobic exercise (think of it like strength training for your glutes). So yes, sprinting can help lift and build those glutes!

How to Sprint for a Bigger Butt

To start building a firmer, shapelier backside, try this beginner-friendly sprint routine a few times a week. Not only will it work those glute muscles, but it can also help boost your speed and stamina.

Beginner Sprint Workout

  1. Warm-up: Start with a brisk walk or light jog to get your muscles moving.
  2. Moderate Sprint: Do your first sprint at around 50-60% of your max effort for about 30 seconds.
  3. Recover: Slow down to a walk for 60-120 seconds to catch your breath.
  4. Pick up the Pace: Sprint again, this time at 70% effort for 30 seconds.
  5. Recover: Walk or slow down for 60-120 seconds.
  6. Go Harder: Now, sprint at 80% of your max effort for 30 seconds.
  7. Recover: Walk or slow down for another 60-120 seconds.
  8. Repeat: Keep up this routine for about 20 minutes, increasing your effort to challenge yourself.

Give this routine a try, and remember that sprinting can help grow those glutes while keeping you fit and fast on your feet!
