SweatStack Profiling

Unstructured athlete profiling for cyclists and runners.

Lab-grade results from the field.

The problem

Lab testing is expensive, invasive, and doesn't scale. Structured field testing is time-consuming and disrupts carefully periodized training plans. Most profiling solutions require inserting specific testing sessions, which breaks up training flow and complicates AI-generated periodization.

The solution

• Input: mean-max data from freeform training.
• Method: automatically detects maximal efforts and estimates physiological metrics using metabolic modelling.
• Output: VO2max, MLSS, FatMax, substrate utilization, training zones, and more.

Why use SweatStack Profiling?

• No lab testing required. Only needs activity data.
• No structured testing required. Only needs freeform training data.
• Scalable. Works for any number of athletes, with no manual labor.
• Differentiates your product. Insights beyond FTP-based training zones.
• Zero hardware investment. It's just software.
• Non-disruptive. Maintains training plan integrity.
• Multi-sport. Works with cycling and running.

Perfect for AI training apps

SweatStack Profiling integrates with AI training platforms without disrupting periodization:

• No plan modifications needed. Insights come from existing AI-generated workouts.
• Continuous background profiling. Profiles update as athletes complete regular training.
• Plan-agnostic. Works with any training approach.
• Preserves training integrity. No need to insert structured testing sessions.

Your AI continues planning optimal training. SweatStack quietly builds comprehensive athlete profiles from the workouts you're already prescribing.
