Skinny-gainer full-body mass session
Beginner · Under 25 · ~50 min
One full-body session built to add size when you're eating big and struggling to grow. Below is a research-backed prompt for ChatGPT, Claude or Gemini, copy it, paste the reply into sweatcue, and run the whole strength workout hands-free.
Session at a glance
This is how sweatcue structures the session once you paste it in, timed blocks with auto-starting rest and spoken cues. Figures are read from the prompt itself.

Why it's built this way
Compound lifts taken close to failure (about 1-3 reps in reserve) across roughly 10 hard sets per muscle a week drive hypertrophy; rep ranges from ~6 to ~15 grow muscle similarly when sets are taken near failure. Rest of 2+ minutes on big compounds preserves volume. Muscle gain still requires eating enough, training organizes the surplus, it doesn't replace it.

Who this workout is for
Built with one person in mind: Naturally skinny and struggling to grow, mass-focused, eating-implied training.
- You’re a beginner-level trainer and you want to build visible muscle.
- You have access to the kit it calls for: barbell, dumbbells, bike.
- You want a single, repeatable strength workout you can drop into your week.
Who should adapt or skip it
- It’s low-risk for healthy adults. Scale the loads and reps to your own level rather than copying the top of every range on day one.
- As with any new routine, check with a clinician first if you have a medical condition, are injured, pregnant, or returning from a long lay-off. This is general information, not medical advice.
What a 2-week plan looks like
A single session works best on a repeating weekly rhythm. Here’s a simple, balanced two-week block at about 3 sessions a week, on non-consecutive days so you recover between them:
| Mon | Tue | Wed | Thu | Fri | Sat | Sun | |
|---|---|---|---|---|---|---|---|
| Week 1 | ● | · | ● | · | ● | · | · |
| Week 2 | ● | · | ● | · | ● | · | · |
● This session· Rest, a walk, or light mobility
Keep session days apart where you can, and adjust for how you feel. When you paste the AI’s reply into sweatcue, each session runs hands-free with spoken cues and timers.
Run it hands-free in sweatcue
sweatcue is an AI workout dashboard: paste the AI's reply and it runs the whole session on screen and out loud, auto timers, spoken cues for every set, rest and rep, and your live numbers. The AI writes it; sweatcue runs it.
