Tempo and sprint engine run
Advanced · 40–54 · ~35 min
A 35-minute mixed run blending a threshold tempo block with short flat-out sprints. Below is a research-backed prompt for ChatGPT, Claude or Gemini, copy it, paste the reply into sweatcue, and run the whole run 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
This single session mixes two distinct stimuli: a threshold/tempo block to push the aerobic-power and lactate-handling end, and short maximal sprints for neuromuscular speed. It's a sensible hard day, but the broader evidence (Seiler, Stöggl & Sperlich) is that fitness gains come mostly from keeping the majority of weekly volume easy and reserving a small share for genuinely hard work. Treat this as one of your one or two hard sessions, not the everyday template.

Who this workout is for
Built with one person in mind: 40s, experienced, power, engine and conditioning.
- You’re an advanced-level trainer and you want to get measurably stronger.
- You have access to the kit it calls for: just you (a watch helps).
- You want a single, repeatable run you can drop into your week.
Who should adapt or skip it
- The jumping and high-impact work isn’t ideal if you’re pregnant, managing a heart condition, or nursing a knee, hip or ankle issue, swap in the low-impact variations or choose a steady session instead.
- It pushes close to heavy or near-failure effort. If you’re brand new to lifting, build technique on lighter sessions first, and skip the near-maximal loading if you have unmanaged blood pressure or a recent injury.
- 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 or an easy walk
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.
