Strong is designed for logging barbell sets in a traditional gym. TrainFlow is built for the mobility tutorials, physical therapy routines, and skill drills you follow on YouTube.
We respect Strong. It is built for a different purpose. Here is how we differ when it comes to training with video.
Strong is one of the most reliable and beloved workout loggers on the market for standard barbell and dumbbell weightlifting. Here is where Strong excels:
Entering weights and reps is lightning fast with a minimal, grid-style layout that stays out of your way during heavy compound sets.
Allows you to create a personalized dictionary of weightlifting movements with custom tags, body parts, and historical 1RM tracking.
Excellent for saving classic powerlifting and bodybuilding splits (Push/Pull/Legs, Upper/Lower) so you can run the exact same sets week after week.
However, if your training relies on follow-along videos, YouTube tutorials, or athletic skill drills, Strong introduces severe session friction:
You cannot embed YouTube videos, save exact timestamp bookmarks, or reference coach instructions. The interface is strictly text and numbers.
Drills like basketball ball-handling, boxing padwork combinations, dance 8-counts, or mobility flows do not fit into a rigid 'weight × reps' spreadsheet cell.
To train with video in Strong, you must run YouTube in Picture-in-Picture or switch between apps constantly, disrupting focus and timer countdowns.

Compare the actual daily friction of tracking a video workout in both tools:
Open YouTube to find your training video tutorial.
Watch the first movement, memorize the form cues, and pause the video.
Switch to Strong, search or create the custom exercise, and log your set.
Switch back to YouTube, scrub through the timeline to find the next drill.
Switch back to Strong to write down notes and log the next set.
Import the YouTube video link once on your desktop or phone browser.
Slice the video into reusable actions with exact start and end timestamps.
Arrange those actions into a routine with sets, duration, or rep targets.
Launch the routine on mobile: the video player locks to the active clip.
Log your reps with simple tap dials directly beneath the video reference.
Traditional workout loggers like Strong were conceived during the era of clipboard-and-pencil gym notebooks. They excel at recording numerical strength variables: barbell load in kilograms or pounds, target repetitions, and resting intervals between bench press sets. For a powerlifter following Starting Strength or 5/3/1, this model is simple and effective.
However, modern fitness has evolved dramatically. Today, millions of athletes and fitness enthusiasts learn technique from YouTube: physical therapy rehab progressions (such as Knees Over Toes or Squat University), basketball shooting mechanics, boxing striking combinations, calisthenics skill progressions, and HIIT interval circuits. In this visual training environment, the primary challenge is not just typing a number—it is reviewing the coaching cue and executing the movement in rhythm.
Attempting to track visual training inside Strong creates constant friction. The athlete watches a 15-minute tutorial, pauses to switch to Strong, creates a text placeholder, and tries to memorize the exact coaching cue. When repeating the drill next week, the original video context is lost, forcing the athlete to search YouTube again.
TrainFlow solves this by placing video at the center of the training workflow. You can import any public YouTube video on desktop, clip the exact 10-second drill demonstration, configure target reps or duration, and launch an interactive mobile workout that loops the visual guide right beside your active rep dials.
You don't have to abandon your current setup. Our tools can complement each other to give you the perfect hybrid training workflow.
Use TrainFlow to follow and slice physical therapy mobility videos, then switch to Strong to record your main squat and bench press sessions.
You do not have to discard Strong if you love its powerlifting log. Use TrainFlow to turn video tutorials, mobility routines, and athletic skill drills into structured visual guides. When you transition to pure heavy barbell lifting, continue using Strong to record your absolute strength PRs.
Paste any YouTube training clip or drill tutorial below. TrainFlow will instantly prepare a preview routine for you.
TrainFlow is optimized for workouts that involve video references and visual drills. You can easily recreate any strength routine in TrainFlow by creating custom actions for each exercise with or without video.
TrainFlow embeds YouTube directly inside the distraction-free mobile web app. When you progress to the next exercise, the player automatically jumps to the bookmarked timestamp for that specific movement.
