BrockGym tells you what to train today, what weight to start with, and when to add load. No calorie counting, no ads, no social feed. It does one thing, and it does it properly.
IT THINKS, IT DOESN'T JUST TAKE NOTES
Most training apps are digital notepads: you write down what you did, and after that you are on your own. BrockGym pre-fills your next session using double progression and your RIR, the reps you left in the tank. The weight only goes up once you clear the top of your rep range cleanly. Not before.
IT KNOWS YOUR EQUIPMENT
BrockGym never suggests a weight you cannot actually load. Enter your dumbbells, bars, plates and machines as separate training locations for home, the gym and travel. Switch location and every number is recalculated to what is really loadable there.
HONEST RECOVERY, NOT AN INVENTED PERCENTAGE
With an Apple Watch, BrockGym reads your resting heart rate and your sleep and shows a traffic light with the reasons spelled out: good, take care, or go easy today. No made-up score. The measurements do not support that kind of precision, and the app says so.

WHAT BROCKGYM DELIBERATELY LEAVES OUT

For everyone who trains seriously, at home and at the gym.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
More control over every exercise:
- A heavier weight is offered before the exercise: increase, adjust it yourself or keep it. If the weight stays, the reason is shown.
- If you had reps in reserve last time, matching reps are suggested.
- Weight only goes up in steps your equipment can actually do.
- Add, remove or skip single sets and warm-up sets with a reason – the reason appears in the workout report.
- More or fewer sets than planned carry over to your next workout.
- During a deload week, only the planned sets are created.
