Helix

Helix is an evidence-based fitness app that builds your training program from scratch, adapts it as you progress, and puts an AI coach in your pocket.

TRAINING
Helix generates a personalised lifting program based on your experience, available equipment, schedule, and goals. Block periodization, progressive overload, and exercise rotation are handled automatically — you just show up and train.

Programs cover 3 to 6 days per week across multiple splits (full body, upper/lower, PPL, and hybrids). Every exercise comes with technique cues and the research behind why it's in your program.

AI COACH
Your coach has your full profile, workout history, and body composition open — so you get real answers, not generic advice. Ask it to change an exercise and it proposes ranked, research-backed alternatives you apply in one tap. It remembers your injuries, dislikes, and goals, adjusts your program and calorie targets, and writes you a plain-language review of your training every week.

NUTRITION
Log food by voice or barcode. Helix calculates your daily targets from your weight, goal, and training volume — and adjusts them automatically on training vs rest days.

PROGRESS
Track strength bests, body composition, weekly volume, and muscle recovery. See exactly where you're improving and where you're falling behind.

RECOVERY
Connects to Health Connect to read your sleep and resting heart rate, and flags when you need to back off.

Built on peer-reviewed research.

Helix is free to use. Unlock the AI Coach and smart nutrition with Helix Pro.
