Recovery stacks: What athletes are using and where spa therapy fits in

Walk into any gym in the UK right now and you’ll hear people talking about recovery almost as much as training. Creatine cycles, magnesium before bed, electrolytes for long sessions - the modern athlete’s toolkit has evolved. 

However, there’s a missing piece in many ‘recovery stacks’ - an integrated approach to spa therapy. Not as indulgence or a once-a-year treat, but using the spa experience to support and inform fitness goals and performance alongside all those other trending elements.

In this article we look at some of the most popular tools athletes are using for recovery, what they do, and where spa therapy fits in for real, measurable benefits.

What are ‘recovery stacks’?

Perhaps a contender for 2026's phrase of the year, a 'recovery stack' is simply a way of describing a combination of tools used consistently to improve training, reduce injury risk and maintain performance. For most gym-goers, runners and weekend warriors, the most popular recovery stack typically includes something like this:

1. Creatine

A trending compound appearing on influencer reels around the world, creatine is said to:

• Improve strength, power output and muscular endurance
• May support recovery by improving cellular energy availability

2. Magnesium glycinate

Magnesium glycinate is another supplement making the social media rounds, combining mineral magnesium and an amino acid. It's said to:

• Support muscle relaxation and nervous system balance
• Often be used to reduce cramping and improve sleep quality

3. Electrolytes (Sodium, Potassium, Chloride)

Electrolytes are considered essential for general functioning, and are generally gained from our foods:

• Essential for hydration, nerve signalling and muscle contraction
• Particularly important for endurance athletes and heavy sweaters

4. Omega-3 fatty acids

Healthy fats that deliver a variety of benefits, Omega-3 fatty acids are said to deliver a variety of benefits, including:

• Anti-inflammatory properties
• May reduce delayed onset muscle soreness (DOMS)

The key line of thinking is that supplements support recovery from the inside out, although the depth of that benefit varies, and importantly, supplements should always be taken on the advice of an expert.

Mapping recovery goals to spa treatments

Spa treatments are often considered a luxury, but their benefits can be as wide reaching as the variety of treatment options themselves. For the goal-driven, athletically-inclined amongst us, there’s an opportunity to think about spa treatments as part of our physical recovery, just like protein or sleep, linked to specific outcomes. For example:

Reducing inflammation and soreness

Recovery goal: Lower muscle soreness, improve circulation, speed up recovery.

Spa tools that may help:

• Hydrotherapy pools
• Cold plunge pools
• Contrast therapy

Cold exposure can temporarily reduce inflammation and perceived muscle soreness, raising the profile of contrast therapies amongst sports fans and gym goers. In line with that, hydrotherapy — using water temperature and pressure strategically — has a long history in sports medicine, and continues to be an intrinsic part of many spa experiences. 

Releasing muscle tension

Recovery goal: Improved mobility, reduced stiffness, preventing injuries.

Spa tools that help:

• Sports massage
• Deep tissue massage
• Thermal suites 

Massage has been shown to improve blood flow, reduce muscle tension and support parasympathetic (rest-and-digest) activation — all of which is crucial for recovery.

Supporting nervous system recovery

Recovery goal: Improve sleep quality, stress resilience and training consistency.

Spa tools that help:

• Sauna
• Steam rooms
• Calm, tech-free environments

Heart Rate Variability (HRV) improves when the nervous system spends more time in a relaxed state. Heat exposure followed by rest has been linked to improved relaxation and sleep, especially when combined with good sleep hygiene.

Contrast therapy: The bridge between gym and spa

Contrast therapy — alternating hot and cold exposure — is where modern gym recovery and spa environments overlap perfectly.

Typically you would spend:

• Five to 10 minutes in a sauna or steam room
• Use a cold plunge pool
• Rest for a few minutes
• Repeat for two to three cycles

Why athletes use it contrast therapy to:

• Improve circulation through vasoconstriction and vasodilation
• Help manage soreness
• Create a strong nervous system reset

Many athletes already use ice baths or cold showers at home. The spa environment simply allows this to be done more consistently, more comfortably, and with better temperature control.

Recovery stacks in practice: Sport-specific recommendations

Not all athletes recover the same way, and as such, recovery stacks can be tailored to match your training. For example, here are some ideas for spa additions to recovery depending on different activities: 

Runners

Primary stress: Repetitive impact, lower-body fatigue, connective tissue strain

Spa ideas:

• Hydrotherapy pools 
• Sports massage 
• Contrast therapy 

Strength training

Primary stress: Muscle damage, joint loading

Spa ideas:

• Deep tissue or sports massage • Sauna for nervous system recovery • Occasional cold plunge to manage soreness 

Cyclists

Primary stress: Long-duration fatigue, hip flexor tightness, posture-related tension

Spa ideas:

• Steam rooms to loosen hip flexors and lower back
• Massage targeting glutes, hip flexors and neck
• Hydrotherapy to reduce leg heaviness

Why spas are becoming serious recovery spaces

Modern spas aren’t just about pampering - they’re evolving into multi-disciplinary recovery environments with a variety of offerings for different wants and needs. For example, SENSORY Wellbeing at Pan Pacific London prides itself on data-driven facilities featuring reports and biofeedback for optimised fitness.

Athletes want:

• Measurable benefits
• Efficient recovery
• Environments that support both physical and mental reset

That’s exactly what spa destinations offer. For athletes and gym-goers, spas aren’t just about luxury;  they’re about longevity, consistency and performance. When used intentionally, spa experiences become the missing layer that turns a good recovery stack into a great one, and keeps you training hard without burning out.
