How do I actually follow this strength workout once the AI writes it?

Paste the AI's reply into sweatcue. It structures the session into timed blocks with auto-starting rest timers and calls every set, rest and rep out loud, so you train hands-free instead of scrolling a chat window.

The prompt

Copy the complete prompt (it wraps the request below so the AI returns a clean, runnable session).

I'm a skinny beginner male under 25 trying to gain muscle as a hardgainer while eating in a surplus. Build me an 8-week, 4-day-a-week upper/lower split that prioritises heavy compound lifts and keeps cardio minimal so I don't burn off my calories. Each session starts with a 6-minute warm-up (light cardio + 2 ramp-up sets). Upper days: bench press 4x5-8, barbell row 4x6-8, overhead press 3x6-10, lat pulldown 3x8-12, plus one arm exercise 2x10-15. Lower days: back squat 4x5-8, Romanian deadlift 3x6-10, leg press 3x8-12, leg curl 3x10-15, standing calf raise 3x12-15. Use ~2-3 reps in reserve on compounds, ~1-2 on isolations, rest 150-180s on the big lifts and 60-90s on the rest. Give me a week-by-week progression: add weight or a rep when I clear the top of a range, and include a lighter deload in week 5. Cap cardio at two easy 20-minute zone 2 walks per week. Tell me what to track.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Roughly 10+ hard sets per muscle per week, spread over 2 sessions each, supports steady hypertrophy in beginners; heavy compound work in lower rep ranges builds strength that lets you add load over time. Excessive concurrent endurance training can blunt hypertrophy, so keeping cardio low and easy is reasonable when size is the priority. Periodic deloads manage fatigue.
