Numbers first. Guesswork later.

Three quick calculators we built for our own members. Free to use, nothing to sign up for, and every result explains what to actually do with it.

One-rep max calculator

Enter a weight and reps you've actually lifted and get your estimated 1RM plus a full training percentage table.

Your daily calorie target and protein floor based on bodyweight, activity and whether you're cutting, maintaining or building.

Score how wound up you are right now and get the breathwork technique that fits your state today.

Partnexa turns these targets into a week-by-week training and recovery plan built around your goal, experience and equipment.
