Summer comes around and for many of us, our routine changes.

During winter, we settle into the rhythm of climbing and training indoors. Then summer arrives, and suddenly, we have other priorities: You want to get outside. Weekends are dedicated to trips and weather windows. You’re traveling, the kids are off school, and friends want barbecues, hikes, and late evenings outdoors. (Frozen margs, anyone? 🍸)

You probably still care deeply about improving as a climber – but no longer want your life organised entirely around training and being indoors at the climbing wall or gym.

And honestly, that's completely healthy!

But a teeny tiny nervous voice in the back of your head is whispering: “If you skip your training, you’re going to lose all your gains.”

It feels like your options are limited:

1. Try and smash out all your summer fun alongside your full training regime, only to end the summer exhausted (and possibly injured!) when you should be feeling rejuvenated.
2. Fully embrace a summer off from training: get on the real rock and climb, pass the time relaxing, having fun, or looking after the kids. And come back in the autumn weaker and disheartened.
3. Make an attempt at something in between… but how much is enough?

In sports science, we borrow a concept from pharmacology called the Minimum Effective Dose (MED), and it is the secret to enjoying your summer without losing your progress.

Instead of constantly asking, “How much training can I fit in?” you can ask yourself, “What is the smallest amount of training I need to maintain performance while prioritising the rest of my life?”

What ‘Minimum Effective Dose’ Actually Means

In medicine, the minimum effective dose is the smallest amount of a drug that will produce the desired medical outcome. If one paracetamol cures your headache, taking four doesn't cure it 'better' – it just damages your liver…

In fitness, your training is the drug. Minimum effective dose is the least amount of training stimulus needed to produce or maintain a meaningful adaptation. It is not the maximum recoverable volume, nor is it the volume that makes you feel like you've worked hard. It is just enough.

The goal of training over summer is to train the smallest amount you can indoors in the gym to maintain adaptations (typically strength, in this context), leaving you with maximum time and energy for the rest of your life.

Sport science consistently shows us that you can maintain your strength and muscle mass on a fraction of your winter training volume, provided the intensity remains high.

A well-written plan that focuses on hitting your minimum training dose should have you leaving the summer as strong as you entered, fully satisfied that you prioritised what you wanted to.

Want someone else to handle the recalibration? Working out exactly how much to dial back, which sessions to keep at full intensity, and when to fully step back is the kind of thing a coach does in their sleep. Our Climbing Training Plan PLUS pairs you with one of our expert coaches who writes a plan around your life and edits it whenever your week changes, whether that's a last-minute Font trip or a sunny outdoor session that replaces your hangboard session.

Summer Priorities and Total Load

Many climbers fall into the "more is better" trap – but the reality is they don't plateau because they train too little, but because they are chronically under-recovered.

This issue peaks during the summer in two main ways:

1. Layering intense outdoor weekends on top of your indoor training. Climbing performance is highly sensitive to cumulative fatigue. While you might easily manage your normal gym workload on its own, adding the heavy physical demands of outdoor climbing pushes your total workload far past what you can actually recover from. As a result, every session begins to feel mediocre because you aren't entering it fresh and rested.

2. An elevated allostatic load. Allostatic load is the combined physical and mental strain from life outside the gym – but we rarely adjust our indoor training to accommodate it. Factors like irregular sleep, childcare, travel, camping, and just generally socialising more after work (those darn frozen margs) all add up. When these lifestyle factors increase your allostatic load, it drives up your Rate of Perceived Exertion (RPE), literally making your project feel harder!

A smart summer training plan adjusts your total workload to fit around your life; it doesn’t just power on as before.

The Core Principle: Train Less

One of the most valuable insights from strength and conditioning research is that maintaining an adaptation requires significantly less training volume than building it. You might need months of dedicated progressive overload to gain a 10% increase in finger strength, but preserving that hard-earned finger strength requires surprisingly little.

Physiological data shows that you can successfully maintain top-end strength and power at a reduced volume, provided the training intensity remains high.

The General Rule

Across strength research, maintenance typically looks like:

The key idea: Volume drops the most. Intensity drops the least.

For example:

• Fingers: A single, high-quality, high-intensity finger strength session per week can comfortably maintain maximum recruitment and strength.

• Power: A short, low-volume board session or a few focused explosive movements on boulders preserve strength & power.

• Strength & Conditioning: 2-3 sets at high intensity, 1-2 times per week per muscle group, should be sufficient to maintain strength.

• Skill: Outdoor climbing itself serves as the ultimate functional tool to maintain real-world movement skills and tactical efficiency.

A Smarter Summer Structure: Layer Your Priorities

Here is a helpful way to break up your training into distinct layers or focuses, each with a different priority.

Priority 1: Outdoor Climbing

When the connies are good, outdoor climbing isn't an ‘extra’ activity added on top of a training plan – it is the primary training stimulus. If performing outdoors is your main goal, then training doesn't get any more specific than that! Getting on the rock is unparalleled for developing technique, movement efficiency, route reading, and pacing. Treating outdoor climbing as supplementary to a full gym workout is how overuse injuries can happen. A full day at the crag already provides a significant portion of your required weekly training load.

Priority 2: Preserve Baseline Finger Recruitment

To protect your fingers without accumulating fatigue, implement a minimal finger strength protocol once a week.

For example, a minimal 20-minute home hangboard session consisting of 5-6 high-quality maximal hangs with rest before your next outdoor/try-hard session, will cleanly preserve your baseline finger strength through the summer months.

Priority 3: Time-Efficient Strength Maintenance

Off-the-wall strength & conditioning is our final priority, particularly focusing on maintaining shoulder and pull strength. You want short, hard sessions that take up minimum time, but yield the maximum output.

A targeted, 45-minute strength session performed once or twice a week should be enough to maintain strength. Focus on compound movements like pull-ups and low rows for pull strength, push-ups or dips for push strength and shoulder stability, and squats or deadlifts for posterior chain strength and lower body stability.

Compound movements target multiple muscle groups at the same time; this minimises your recovery debt, as you are able to stimulate a wide range of muscles with fewer total exercises.

Training Around Family, Travel, and Busy Schedules

For climbers with children or demanding careers, energy can be a finite resource. Success in these phases is completely defined by consistency and flexibility. You are significantly more likely to stay consistent and see long-term progress when you let go of any rigid expectations, and enjoy, appreciate, and utilise the time you do have available.

• The 20-Minute Window: Utilise brief home sessions, training little and often during nap times or quiet windows.

• Supersets and Clusters: Combine basic exercises – like supersetting your dumbbell work – to save time and keep workouts hyper-efficient.

• Holidays and Planned Rest: Strength detrains way more slowly than many climbers worry about. A week or two completely away from structured training often carries an added recovery benefit. It allows any ongoing connective tissue irritation to chill out, metabolic and CNS fatigue to reset, and psych to fully recharge.

The ‘Two Good Sessions’ Rule

A fundamental principle for summer is that two high-quality sessions beat five compromised ones. The quality and intent of your session matter far more than the total hours logged on an app or spreadsheet.

As counterintuitive as it feels, some of the most effective training sessions are the ones we leave with a little still in the tank – enough stimulus to adapt, without accumulating unnecessary fatigue.

When you stop training simply to feel tired and instead train to achieve your goals, you free up massive amounts of time and physical and mental energy for actual climbing and enjoying summer.

Take out the guesswork 🤷 Our coaches are experts. They've helped thousands of climbers just like you manage their training load to match their goals and priorities. If you're constantly worrying whether you're doing enough, why not put your mind at ease this summer and trust a Lattice coach?
