About this app

Dopamine HIIT is the official Train with Flex training app, built for clients of certified personal trainer Rafique "Flex" Cabral.

This is more than a workout log. It's a structured 12-week training experience designed by Flex himself, tracked across every set, every meal, every habit, every day.

WHAT YOU GET

• Personalized Programs: Your phase, your block, your week, your day. Every workout is hand-built by Flex based on your assessment and goals.

• Built-In Circuit Runner: Round-by-round guidance through warm-ups, circuits, and rest. Built-in timer, automatic ghost-carryover of your last performance, and clean logging of sets, reps, and weight.

• Meal Tracking: Log breakfast, lunch, dinner, and snacks. See your daily macro split and weekly calorie trends at a glance.

• Habit Building: Daily habits, weekly views, streaks. Five quick taps, and you're done.

• Goal Tracking: Set your North Star and the milestones to get there. Track RPE trends, personal bests, and body composition over time.

• Schedule: See your sessions, book new ones on Flex's calendar, and never miss a workout.

• Push Notifications: Stay accountable with check-ins from Flex.

WHO IT'S FOR

Train with Flex clients, current and new. Whether you're walking into the gym for the first time or coming back after a decade away, Dopamine HIIT meets you where you are and tracks every step of the climb.
