Written by: Jes Butler

Outdoor Fitness, Paddleboarding, and Wellness in the Texas Heat

Summer at Lake LBJ brings an open invitation to all things outdoors. For many visitors and locals alike, fitness and movement routines naturally make the transition outside, creating opportunities to combine wellness goals with the beauty of lake life. Swimming, kayaking, wake surfing, paddleboarding, and outdoor fitness classes all become part of the rhythm of summer in the Highland Lakes.

Whether you're planning a weekend getaway to Marble Falls, spending the season on Lake LBJ, or searching for active things to do in the Highland Lakes, exercising outdoors offers a unique way to experience the area. With a few simple precautions, it's possible to safely leave the gym behind and embrace movement on the water.

Why Summer Exercise at Lake LBJ Requires Extra Planning

While outdoor fitness has countless benefits, Texas summers demand additional awareness. High temperatures, direct sun exposure, and humidity can place significant stress on the body's cooling systems.

Proper hydration is the single most important factor when exercising in the summer heat. Drinking water and electrolyte beverages before, during, and after activity helps the body regulate temperature through sweating and replace fluids lost throughout the day.

Humidity also plays a significant role. The more humid the air becomes, the harder it is for sweat to evaporate. Since evaporation is one of the body's primary cooling mechanisms, high humidity can increase the risk of heat-related illness even when temperatures seem manageable.

Understanding the Heat Index Before Exercising Outdoors

Before heading out for a paddleboard session, morning run, kayak excursion, or outdoor workout, it's important to check more than just the forecasted temperature.

The heat index combines air temperature and humidity to reflect how hot it actually feels outside. On many summer days at Lake LBJ, the heat index can exceed 100 degrees even when the air temperature appears relatively moderate.

As a general guideline:

• Heat index below 90°F: Exercise with normal precautions.

• Heat index between 90°F and 103°F: Increase caution, hydration, and recovery time.

• Heat index above 103°F: Outdoor exercise may become dangerous, especially during prolonged activity or direct sun exposure.

The National Weather Service regularly issues Heat Watches, Heat Advisories, and Extreme Heat Warnings when conditions warrant additional caution.

Recognizing the Early Signs of Heat Illness

One of the most important skills for anyone enjoying outdoor activities at Lake LBJ is recognizing the warning signs of heat-related illness.

Heat Cramps

Heat cramps are often one of the earliest signs of dehydration and electrolyte imbalance. These painful muscle spasms commonly occur in the arms, legs, or abdomen and can become especially dangerous during water activities.

If cramping occurs while swimming, paddleboarding, or participating in water sports, exit the water immediately and begin rehydrating.

Heat Exhaustion

Heat exhaustion requires prompt attention and may include:

• Excessive sweating

• Muscle cramps

• Weakness

• Dizziness

• Headache

• Nausea

• Clammy skin

If these symptoms develop, move to a shaded or air-conditioned area, begin cooling measures such as cold washcloths or fans, and slowly replace lost fluids.

Heat Stroke

Heat stroke is a life-threatening medical emergency that can occur when heat exhaustion goes untreated.

Symptoms may include:

• Extremely high body temperature

• Confusion or altered mental state

• Hot skin

• Rapid pulse

• Loss of consciousness

If heat stroke is suspected, call 911 immediately.

The Best Times to Exercise at Lake LBJ During Summer

Fortunately, some of the most enjoyable times to move outdoors are also the safest.

Early mornings often offer cooler temperatures, calmer water conditions, and a quieter lake experience. Evening workouts and sunset sessions can provide another opportunity to stay active while avoiding peak daytime heat.

At Board & Body, our Signature Saturday paddleboard fitness classes meet at 8:00 a.m. throughout the summer months to help guests enjoy the benefits of outdoor fitness before temperatures begin to climb. We also offer occasional Sunset Sessions and private group experiences that take advantage of cooler evening conditions.

Guests are encouraged to bring water bottles and allow time for recovery in an air-conditioned environment before continuing with other outdoor activities.

All classes are led by a First Aid and CPR-certified instructor with additional training in recognizing and responding to heat-related illness.

Whether you're paddleboarding, wake surfing, kayaking, swimming, or simply enjoying a day on the water, these precautions can help you stay safe:

• Wear light-colored, loose-fitting clothing.

• Schedule activity during morning or evening hours whenever possible.

Special attention should be given to individuals who may be more vulnerable to heat-related illness, including:

• Pregnant women

• Older adults

• Athletes wearing heavy or non-breathable equipment

These groups may be at increased risk for dehydration and heat stress and should be monitored carefully for early warning signs.
