RMR, where many plans go wrong
A single visit. One clear picture.
Every test returns a precise, clinical-grade reading. Book one, or stack two or three into one appointment at the Southpoint location and see how your whole body is working at once.
DEXA Body Composition Scan
The reference standard for reading a body. One quiet open-air pass separates fat, lean tissue, and bone, region by region, at ±2% clinical accuracy. The scale gives you one number. A DEXA scan shows what it is made of.
VO₂ Max Test
VO₂ Max is the ceiling on your aerobic capacity, and the fittest carry a 5x lower mortality risk than the least fit (Mandsager et al., JAMA 2018). You move while we measure your engine directly, then leave with training zones set to your own number, not a watch estimate.
Resting Metabolic Rate (RMR) Test
Calorie targets pulled from an online formula are a guess, and that guess is where a lot of nutrition plans quietly stall. A few relaxed minutes breathing into a mask reveals the calories your body actually burns at rest, so your plan starts from your real number.
Measure. Track. Understand.
From the moment you book to the moment you leave with answers, here is how your visit to Southpoint unfolds.

A DEXA scan for body composition, a VO₂ Max test for cardio fitness, and an RMR test for metabolism. We also offer biomarker lab tests, GLP-1 weight loss support, and red light therapy. Each core test returns a clinical-grade reading, and a specialist walks you through it during the same visit.
The DEXA scan itself runs about 8 minutes; with check-in and a walk-through of your results, plan on roughly 20 minutes. A VO₂ Max test takes about 15 minutes to run, or about 35 minutes start to finish. The RMR test also runs about 15 minutes, or around 25 minutes total. Book all three in one visit and you are usually done in about 75 minutes.
