If you're someone aiming to push your physical limits - whether that’s tackling ultramarathons, competing in Ironmans, or simply becoming stronger and more resilient - then lifting heavier weights is essential. But let’s be honest: stepping up to heavier loads can be intimidating.

The good news? There’s a path to follow to build strength in the gym - and it doesn’t involve guesswork. In this post, we’ll break down five key strategies that will help endurance athletes confidently lift heavier, get stronger, and elevate your training game.

1. Education: Know the "Why" Behind the Weight

Before you even touch a barbell, it’s crucial to understand why lifting heavier matters. This isn’t about ego -it’s about performance, injury prevention, and unlocking your body’s potential.

Progressive overload is the foundation here: over time, you want to increase resistance to build strength. But strength training should be tailored to you. That means identifying the right exercises based on your injury history, equipment availability, and movement patterns.

Not everyone will be using a barbell straight away. Start where you are - maybe that’s bodyweight movements or resistance bands - and build from there. Define “heavy” in relative terms: 50%-100% of your body weight is often a solid benchmark.

2. Preparation & Visualisation: Prime Your Body and Mind

Never underestimate the power of a good warm-up before your strength sessions. Olympic lifters spend up to an hour preparing their bodies before a session and for good reason.

Use warm-ups and prep sets (think bodyweight variations, light barbell work, etc.) to:

Activate muscles
Reinforce proper technique
Gauge how your body feels that day
Mentally visualise the heavier lift ahead

This isn’t just physical - it’s psychological. The better you prepare, the more confidently you can step under the bar.

3. Training Aids: Use Tools to Bridge the Gap

Confidence doesn’t mean you should jump into strength training unassisted. Training aids are your friends when progressing toward heavier loads. Some great examples:

Box or bench behind you during squats to reinforce depth and provide safety
TRX or a wall to support balance during single-leg RDLs or lunges
Resistance bands for assisted chin-ups or dips

These tools help you maintain form and stay safe, so you can load heavier with confidence, not hesitation.

4. Follow a Structured Strength Training Plan

“Winging it” is not a strategy. A well-designed, periodized plan gives you a clear roadmap, tracking:

Reps
Sets
Load progression
Recovery phases

Progressions should be visible and logical. You might start with 3x6 at a light weight and progress to 4x8 at a heavier load over a few weeks. Seeing that progression in your strength and muscle builds belief in your ability, and keeps motivation high.

Plus, having a coach or support system gives you feedback loops - you can adjust based on how you're performing and how you're feeling.

5. Ask for Help

Sounds simple, but it’s often the hardest step: ask for guidance.

Whether it's a coach, a knowledgeable gym training partner, or even a PT passing by, don’t be afraid to ask questions:

“Is my form okay?”
“What would you change here?”
“How can I improve this movement?”

A fresh set of eyes can help uncover weak links or inefficiencies - and unlock your next breakthrough.

Finally - Strength Is Earned, Not Given

Lifting heavier isn't just about brute force - it’s about strategy, structure, and self-awareness. You can absolutely build the strength you need to meet your goals. It just takes time, commitment, and a willingness to learn.

So whether you're a seasoned athlete or just getting started, remember these five things:

Understand your why
Prepare and visualise
Use training aids to build up
Follow a plan
Ask for help
