The workout: 5 minutes of easy pedalling to warm up, 20 minutes alternating 3 minutes at a moderate effort with 2 minutes easy, and 5 minutes of easy pedalling to cool down. Use the talk test to set effort rather than a particular speed or resistance number, because these vary from bike to bike. Do it 2 to 4 times a week.
Set up the bike first
- Seat height: with the pedal at the bottom of its stroke, your knee should be slightly bent (roughly 25 to 35 degrees), not locked straight.
- Seat position: with the pedals level, your front knee should sit roughly above the ball of your foot.
- Handlebars: high enough that you can hold them with relaxed shoulders and a slight bend in the elbows.
- Recumbent bikes: adjust the seat so your knee is slightly bent at full extension.
Effort levels
| Level | Effort (1 to 10) | Talk test |
|---|---|---|
| Easy | 3 to 4 | Can chat comfortably |
| Moderate | 5 to 6 | Can talk in sentences, a little breathless |
| Hard | 7 to 8 | Only a few words at a time |
Increase effort by adding resistance, pedalling faster, or both. A comfortable cadence for many beginners is around 70 to 90 revolutions per minute if the bike shows it.
The 30-minute workout
| Time | Block | Effort |
|---|---|---|
| 0 to 5 min | Warm-up, light resistance | Easy |
| 5 to 8 | Steady push | Moderate |
| 8 to 10 | Recovery | Easy |
| 10 to 13 | Steady push (add a little resistance) | Moderate |
| 13 to 15 | Recovery | Easy |
| 15 to 18 | Steady push | Moderate |
| 18 to 20 | Recovery | Easy |
| 20 to 23 | Steady push | Moderate |
| 23 to 25 | Recovery | Easy |
| 25 to 30 | Cool-down, light resistance | Easy |
4-week progression
- Week 1: 20 minutes all at an easy-to-moderate steady pace, 3 times.
- Week 2: the 30-minute workout above, 3 times.
- Week 3: make the moderate blocks 4 minutes and recoveries 1 minute.
- Week 4: add one session, or turn the last push into 1 minute hard plus 2 minutes moderate.
Tips for comfort
- Saddle soreness is common in the first sessions and usually eases; padded shorts or a gel seat cover help.
- Keep your knees tracking straight over your feet, not out to the sides.
- Stay hydrated and keep a towel nearby.
- Finish with calf, quad, hamstring and hip flexor stretches from the 5-minute cool-down.
Why a bike is a good beginner choice
Cycling is low-impact, so it is gentle on the knees, hips and ankles, and the seat takes balance out of the equation. It is easy to make it lighter or harder in seconds. Mix it with low-impact cardio at home, an incline treadmill walk or a rowing machine workout for variety.
FAQ
Is 30 minutes on a stationary bike a good workout?
Yes. Thirty minutes at a moderate effort, five days a week, meets the common guideline of 150 minutes of moderate aerobic activity.
Upright or recumbent?
Both work. A recumbent bike supports your back and is easier to get on and off; an upright bike feels more like outdoor cycling.
