Eat more fish, but not that fish
Omega-3 pushes you toward fish, mercury pushes back. How gostrong's solver balances both, plus protein quality, so you never do the arithmetic.

Plans that cite their sources.
gostrong builds your training week and your meal plan with a constraint solver, and anchors every load-bearing number to a published meta-analysis or position stand. When the literature disagrees with popular coaching, the literature wins.

What gostrong does
A solver, not a template
Meal plans and weekly training templates are combinatorial problems. A CP-SAT solver satisfies every macro, volume and safety constraint at once, for your body, equipment and schedule.
Diet phases that drive every number
Fat loss, maintenance or muscle gain, each with a rate and a duration. Calorie targets follow the phase and get corrected against your weigh-ins.
Progression that follows your data
Reps progress before load, and a deload fires on performance signals, not on the calendar. Loads always resume from what you actually lifted.
Meal plans and a shopping list
Generated automatically, with a regenerate-day option. The week sums into one shopping line per food, in grams.
A coach that explains itself
Reads training, diet, body and sleep together and tells you which single thing to change first, with a note on the evidence behind it.
The details nobody reads
Weekly omega-3 floors and mercury ceilings from EFSA and the US EPA are hard constraints, so the plan stays safe while you still get food you will eat.
