Your first week is free. A fitness program built around your body, your schedule and the equipment you have, with workouts and meals adjusted every day.
The fitness program that fits you.
Primary builds a workout and meal plan around your body, your goals, the equipment you have and the time you've got, then adjusts it every day from how your training actually went.
GUIDED, SET BY SET
Every session is laid out for you: each exercise with a demo, the sets, reps and load, and a rest timer between sets. Log as you go and move on.
WEIGHT GOES UP WHEN YOU'RE READY
After each exercise, tell Primary how it felt: easy, about right, hard or painful. Loads rise when you're ready, and each muscle gets its recovery time before it's trained hard again.
WORKS AROUND INJURIES
Sore shoulder or knee? Primary swaps in exercises that train the same muscles while sparing what hurts.
GYM OR HOME
Your plan uses the equipment you actually have, from a full gym to a pair of dumbbells in the living room, and fits the time you have that day.
MEALS THAT MATCH YOUR WORKOUTS
Meal guidance in the cuisine you already eat, timed around your sessions, with protein targets and supplement reminders.
CONNECTS TO YOUR HEALTH DATA
Link Apple Health and supported wearables. Sleep, heart rate and activity feed into each day's plan, and your progress, lab results and trends live in one place.
MORE THAN FITNESS
Primary also offers programs designed by physicians and health experts for metabolic health, digestive wellness, sleep, healthy ageing and women's health. If your doctor uses Primary, join their program with an invite code.
HOW IT WORKS
1. Tell Primary your goal, experience, equipment and schedule.
2. Get today's session and meals, ready to follow.
3. Train, log your sets and say how each one felt.
4. Your plan adapts overnight for tomorrow.
FREE FOR YOUR FIRST WEEK
