4 Strength Moves Every Runner Needs to Run Faster

4 Strength Moves Every Runner Needs to Run Faster

Most runners treat strength training like a footnote. A few lunges before a race, maybe some squats when guilt kicks in. Coaches at Life Time, one of the largest premium fitness networks in the US, say that mindset is exactly what's holding runners back from both better times and longer careers.

The evidence backs them up. Studies consistently show that targeted resistance training improves running economy by 2 to 8 percent, which translates to real speed gains without any additional aerobic work. The problem isn't that runners don't know strength training exists. It's that most of them are doing the wrong exercises, or skipping the right ones entirely.

Here's what Life Time coaches actually recommend, and why these four specific moves make the difference.

Why Runners Skip Strength (And Why That's a Costly Mistake)

Running is a sport that rewards volume. More miles, more fitness. That logic is hard to argue with, which is why strength work keeps getting pushed to the back of the training plan. When something has to give on a busy week, the gym session goes first.

But that trade-off has a price. Research published in the Journal of Strength and Conditioning Research found that runners who incorporated structured resistance training twice per week experienced significantly fewer soft-tissue injuries over a training season compared to those who ran only. Tendons, ligaments, and stabilizing muscles don't adapt fast enough to absorb the cumulative load of running without additional stimulus. The road eventually wins.

Life Time coaches describe this as the "resilience gap." Your cardiovascular system can handle more mileage than your structural tissues can sustain. Strength training closes that gap.

Move 1: Bulgarian Split Squats

The Bulgarian split squat is the single most effective lower-body movement for runners, according to Life Time's coaching staff. It's also one of the most consistently avoided exercises in a gym full of runners who claim they "already do legs."

Here's why it matters specifically for running. The Bulgarian split squat loads each leg independently, which mirrors the mechanics of every single stride you take. It builds quad strength, hip flexor length, and glute activation simultaneously. That combination directly improves your ability to generate force through the push-off phase of your gait.

To perform it: place your rear foot on a bench or box at roughly knee height. Lower your front knee toward the floor while keeping your torso upright. Your front shin should stay relatively vertical. Three sets of 8 to 10 reps per leg, with enough load to make the final two reps challenging.

Runners who add this movement consistently report reduced knee pain and improved stride power within four to six weeks. The asymmetry also exposes imbalances between legs that bilateral squats simply hide.

Move 2: Calf Raises (Especially Single-Leg)

The calf complex, including the gastrocnemius and soleus, absorbs roughly 8 times your body weight with each running step. That's not a typo. Yet most runners never train their calves beyond what mileage alone provides, and that chronic underloading is a direct path to Achilles tendinopathy, plantar fasciitis, and calf strains.

Life Time coaches specifically recommend heavy, slow single-leg calf raises performed through the full range of motion. Lower your heel as far below the step as possible, pause, then raise all the way to the top. This eccentric emphasis is what actually remodels tendon tissue and builds the elastic strength that makes running more efficient.

Sets of 12 to 15 reps with added load (a dumbbell in one hand works fine) performed three times per week is the minimum effective dose. Research on recreational runners shows that 12 weeks of progressive calf loading reduces Achilles tendon pain and improves running economy independently of any change in mileage.

If you're ramping up summer training volume, this is non-negotiable. Whether you're prepping for a local 5K or looking at summer heat training strategies that account for physiological stress, your tendons need to be prepared for the extra work before your aerobic fitness pushes you to do more.

Move 3: Kettlebell Swings

Kettlebell swings train the posterior chain, your glutes, hamstrings, and lower back, through a powerful hip hinge pattern. That pattern is essentially a loaded simulation of the drive phase in running. It builds explosive hip extension, which is the primary force-producing action in faster running paces.

There's also a conditioning benefit that matters specifically for runners. Swings are ballistic. They train your nervous system to recruit muscle fibers quickly and forcefully, which is exactly the stimulus that transfers to higher cadence and better stride power. Slow, controlled movements alone don't deliver that neurological adaptation.

Life Time coaches recommend two to three sets of 15 to 20 swings with a weight that demands full hip snap to complete. A 35 lb kettlebell is a reasonable starting point for most recreational runners. Focus on loading the hinge, not squatting the movement down.

The recovery benefits are notable too. Posterior chain work done correctly improves blood flow to the hamstrings and glutes, which are chronically tight and underpowered in runners who train on flat surfaces. Pairing this with adequate protein intake accelerates tissue repair between sessions. Protein and fiber together have emerged as 2026's most evidence-backed nutrition combination for athletes managing high training loads.

Move 4: Single-Leg Deadlifts

The single-leg deadlift is a balance exercise, a hip hinge, a hamstring strengthener, and a glute builder all at once. It's also the movement that most directly trains the proprioceptive stability your ankle and knee need to survive thousands of footstrikes on uneven terrain.

For trail runners specifically, this exercise is essential. But even road runners benefit enormously, because single-leg stability is what keeps your form intact when you're fatigued in the final miles of a long run. Technique breakdown under fatigue is where most running injuries actually happen.

To perform it: hold a light to moderate dumbbell or kettlebell in the hand opposite your standing leg. Hinge forward at the hip while your rear leg lifts behind you, keeping your spine neutral throughout. Lower until your torso is roughly parallel to the floor, then drive back up through the standing heel. Three sets of 8 to 10 reps per leg.

Start lighter than you think you need to. The balance demand is significant enough that most runners need several sessions just to develop the coordination before loading becomes meaningful.

If you're building toward a bigger goal this year, whether that's a trail race or a destination event, planning a trail running trip around your fitness development requires exactly the kind of structural preparation these movements provide.

How to Fit This Into Your Running Schedule

The most common objection is time. Here's the structure Life Time coaches recommend for runners who want to protect their joints and improve performance without overhauling their training week.

• Frequency: Two sessions per week, on non-consecutive days. Ideally placed on the same day as an easy run or as a standalone session, not immediately before a hard workout or long run.
• Volume: Three sets of each movement per session. A complete workout takes 35 to 45 minutes once you're familiar with the exercises.
• Progression: Add load or reps every one to two weeks. Without progressive overload, the structural adaptations plateau quickly.
• Recovery: Allow at least 48 hours between strength sessions. Electrolyte intake post-session matters more than most runners realize. Magnesium and potassium play a specific role in muscle recovery that sodium alone doesn't cover.

Expect the first two to three weeks to feel awkward and humbling. Single-leg movements expose weaknesses that bilateral exercises mask, and that's exactly the point. The discomfort is diagnostic.

What the Research Actually Shows

A meta-analysis of 26 studies found that concurrent training (combining endurance and strength work) improved running economy by an average of 4.6 percent in trained endurance athletes. That number translates to meaningful time improvements at every distance.

Injury reduction data is equally compelling. Prospective studies show that runners who perform at least two strength sessions per week reduce their overall injury incidence by roughly 50 percent compared to run-only training groups. Most running injuries are overuse injuries. They're not accidents. They're the predictable result of insufficient tissue capacity meeting accumulated load.

Some runners also ask about supplementation to support the strength work. The research on creatine for endurance athletes is more nuanced than it is for pure strength sports. Understanding whether a creatine loading protocol is worth it depends on your training structure and goals, but it's worth knowing the evidence before making a decision.

The Bottom Line

Running more is not always the answer. The four moves outlined here, Bulgarian split squats, calf raises, kettlebell swings, and single-leg deadlifts, target the exact structures that running breaks down over time. They're not generic cross-training filler. They're a specific, targeted protocol designed to make your body capable of handling the mileage your lungs already want to run.

Two sessions a week. Consistent progression. Your next PR might not come from a new training plan. It might come from finally showing up in the weight room.
