Off-bike 30/30 leg-power intervals
Intermediate · 40–54 · ~20 min
Bike-free 30-on/30-off intervals that push leg power without the saddle. Below is a research-backed prompt for ChatGPT, Claude or Gemini, copy it, paste the reply into sweatcue, and run the whole HIIT 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
Short, hard intervals are a time-efficient way to improve aerobic fitness and leg power, and bodyweight HIIT circuits are a practical no-equipment option. For a trained cyclist this is a useful cross-training stimulus and adds some impact loading you don't get on the bike, but it won't replace structured on-bike work for cycling-specific endurance. Push the hard intervals genuinely hard for the benefit to show up.

Who this workout is for
Built with one person in mind: 40s–50s, ride regularly, chasing more sustainable power.
- You’re an intermediate-level trainer and you want a bigger aerobic engine.
- You want to train with little or no equipment, this one needs none, bodyweight.
- You want a single, repeatable HIIT workout 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.
- 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 2 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 easy aerobic work
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.
