A good personal trainer tracks your volume, adjusts your routine for fatigue, and tells you when to rest. Better Gym does exactly that, but with 45+ metrics calculated in real time. Free.
It doesn't replace your trainer. It empowers them with data no human can calculate in real time.
$50-100 per session
per month, forever
Your gym absorbs the platform cost
Every metric is backed by sports science research. These aren't made-up numbers. They're proven calculations.
We calculate your estimated one-rep max using three validated formulas:
The system selects the most accurate formula based on your rep range.
We estimate recovery time per muscle group:
Status: Ready / Partial / Needs rest. Updated in real time.
The system automatically detects your current training phase:
We model your fitness state with exponential decay:
Decay adjusted by age. Positive = good form. Negative = overtraining.
Automatically. Without doing anything more than logging weight and reps.
The prediction engine analyzes your history and projects your performance 4 weeks ahead. If you keep your current volume, what will your 1RM be? Do you need a deload? Did your load increase too fast?
Your estimated max strength in 4 weeks, based on your current improvement rate.
Combines fatigue, load spikes and muscle imbalances into a single number.
How much training you need to progress without overtraining.
Low risk. Keep it up.
By entering weight, age, gender, body fat percentage and muscle mass, the system normalizes every calculation. Relative metrics, not absolute. Because a 100kg 1RM doesn't mean the same for someone weighing 70kg as for someone weighing 100kg.
"Being able to see my estimated 1RM go up week by week is the best motivation. And the risk score saved me from a shoulder injury because it warned me about an anterior/posterior deltoid imbalance."
"As a trainer, I use the backoffice metrics to adjust my clients' routines. But the user app is great because they see their progress and stay motivated on their own. Less WhatsApp, more training."
