Island Fitness
South Padre Island, Texas
Island Fitness Member Scheduling
Metabolic and fitness testing is currently available for Island Fitness members during scheduled South Padre Island testing dates.
Choose standalone RMR or VO₂ Max testing, combine both tests, or choose the Midlife Metabolism & Hormone Audit if you want your metabolic data placed inside a broader look at menopause, hormones, nutrition, body composition, strength, sleep, and recovery.
A few things to know before scheduling.
Metabolism and VO₂ testing are wellness and fitness assessments. They are not diagnostic medical tests and do not replace medical evaluation, cardiac testing, or care from your licensed healthcare team.
You may be asked to complete a short screening before testing. Some symptoms, medical conditions, medications, recent illness, injuries, or exercise limitations may affect whether testing is appropriate that day.
For VO₂ testing, you should be able to exercise safely at increasing intensity. If you have known or suspected heart or lung disease, unexplained chest pain, fainting, significant shortness of breath, or concerning exercise symptoms, please speak with your medical provider before booking.
Basic testing prep
You’ll receive location-specific instructions after booking, but in general:
RMR
Morning testing is preferred. Arrive after a normal overnight fast with no food, caffeine, stimulants, or nicotine beforehand. Water is fine. Avoid hard or unusually strenuous exercise for 24 hours before testing.
VO₂ Max
Arrive normally fueled and hydrated. Finish food or caloric beverages at least 4 hours before testing. If caffeine is part of your normal routine, a normal low amount earlier in the day is fine; avoid additional caffeine or stimulants for approximately 2 to 3 hours before testing. Avoid hard or unusually strenuous exercise for 24 hours.
You’ll receive complete instructions after booking.
If you are sick, recovering from a recent illness, injured, or unsure whether you should test, please reach out before your appointment.
