Your first three steps determine your acceleration. Impulse tells you exactly what's happening in each one. Film your sprint in slow motion and Impulse automatically extracts the mechanics that matter: shin angle at ground contact, ground contact time, and flight time across each step. No lab equipment. No sensors. Just your iPhone. The same data that previously required a university motion capture lab is now in your pocket. THE SCIENCE When your shin is vertical at ground contact, force drives straight down — pushing you up, not forward. A forward shin angle redirects that force vector backward, converting it into horizontal velocity. Shin angle is the single biggest mechanical determinant of how fast you accelerate off the line. WHO IT'S FOR Sprinters, football players, basketball players, or any athlete who needs to be faster in their first few steps. If your first step matters, your mechanics matter. WHAT YOU GET Shin angle at each ground contact across your first three steps Ground contact and flight time per step Speed at each step calculated from your footage Session history to track improvement over time See how your mechanics correlate with your speed across sessions HOW IT WORKS Prop your phone at hip height from the side. Film your first 3-4 steps in slow motion. Impulse processes the footage and delivers a full mechanics breakdown in minutes.

LastRep remembers your last set so you always know what to beat. Log a workout and LastRep hands you exact targets for next time. No guessing, no spreadsheets, no rebuilding your program every week. PROGRESSIVE OVERLOAD, CALCULATED Every exercise gets a target based on what you actually lifted. Hit the top of your rep range and LastRep adds weight. Fall short and it asks for one more rep at the same load. Ramp-up sets are detected automatically, so warmups never get treated as working sets. CARDIO PROGRESSES TOO The assault bike, the stairmaster, heavy bag work, the treadmill. LastRep pushes one variable about five percent per session. More minutes, more calories, or more distance, never all at once. A CALENDAR OF YOUR TRAINING Every training day marked. Tap any day to see exactly what you did, edit it, or log a session you forgot. A WEEK THAT BUILDS ON ITSELF Pick your training days and your exercises. LastRep lays out the week, groups related lifts together, drops cardio on the lighter days, and attaches a live target to every entry. Finish the week, rebuild, and next week starts heavier. Push it to your iPhone calendar in one tap. BUILT TO STAY OUT OF THE WAY Around 100 exercises across chest, back, shoulders, arms, legs, core, machines, outdoor, conditioning, and martial arts.
