Stationary bike workout: setup, a steady ride, an interval ride, and a plan for beginners

Every gym has three kinds of stationary bike, and most homes that own one have one of them. The spin bike, sometimes called an indoor cycling bike, puts you over the pedals like a road bike, with a heavy flywheel and a resistance knob. The upright bike has a wider seat and a more upright position. The recumbent bike sits you back in a chair-like seat with the pedals in front of you. All three train the same thing: your heart, your lungs and your legs, at an effort you choose.

This page covers which bike to use, how to set it up, two sessions for a beginner, a four-week plan, what trials of indoor cycling found, and what they found for weight. How hard "easy" is, in heart-rate terms, is on zone 2 cardio; intervals against steady riding in general is on HIIT vs steady-state cardio; and fitting rides around a lifting plan is on cardio and lifting.

Spin, upright or recumbent?

Two studies compared them directly:

• Energy at the same effort. In 30 recreationally active men, average age about 42, who did 12-minute bouts on seven indoor cardio machines at the same hard rated effort and at their maximum, the treadmill drew the most energy, oxygen and heart rate, followed by the stair climber, the elliptical, the spin bike, the upright bike, the rower and, last, the recumbent bike.¹
• Upright against recumbent, to exhaustion. In 18 healthy people who did step tests to exhaustion on an upright bike and on a recumbent bike reclined at 40 degrees, the upright position reached a higher peak power, oxygen uptake and heart rate, and higher power at the lactate and ventilatory thresholds.²

So, roughly: the more upright and forward you sit, the more energy the same effort tends to use. That doesn't make the recumbent bike the wrong choice. It has a back rest, it's the easiest to get on and off, and it's still cardio. The 2024 study's authors make the point themselves: beyond calories, exercise people genuinely enjoy can help them stick with it.¹ Pick the bike you'll ride three times a week.

Setting up the bike

1. Seat height. Stand beside the bike and set the seat at about hip height, then sit and put a heel on the pedal at its lowest point: the leg should be almost straight. With the ball of the foot on the pedal, the knee is then slightly bent at the bottom. A 2011 review of saddle-height research found the methods for setting it varied and weren't well established, and suggested a knee bend of about 25 to 30 degrees at the bottom of the stroke.³ If your hips rock side to side, the seat is too high; if your knee comes up close to your chest at the top, it's too low.
2. Seat position, front to back. On a spin bike, with the pedals level, your front knee should sit roughly over the pedal. On a recumbent bike, slide the seat until the knee is slightly bent with the pedal at its farthest point.
3. Handlebars. High enough that you can reach them with a slight bend in the elbows and without rounding hard through the back. Higher is more comfortable to start with.
4. Feet. The ball of the foot over the middle of the pedal, straps snug or shoes clipped in, so you can push and pull without your foot sliding.
5. Resistance. On a spin bike, never pedal with no resistance at all; a light touch keeps the flywheel from spinning your legs for you. On every bike, start light and turn it up over the first few minutes.

The steady ride

Ride 20 to 30 minutes at a pace you could hold while talking. That's the talk test: in a study of 16 physically active people, holding the last stage at which talking was still comfortable produced a training intensity suited to healthy adults.⁴ The World Health Organization puts moderate activity at about a 5 or 6 on a 0-to-10 scale of effort.⁵

Each of those minutes counts toward the WHO's guideline for adults of 150 to 300 minutes of moderate aerobic activity a week, or 75 to 150 of vigorous.⁵ Three 30-minute rides is 90; walking can make up the rest.

The interval ride

One 12-week interval study on stationary bikes put sedentary men, average age 27, on three rides a week for 12 weeks. One group did a 10-minute ride: a 2-minute warm-up, three 20-second all-out sprints separated by 2 minutes of easy pedaling, and a 3-minute cool-down. The other did 45 minutes of steady cycling at about 70% of maximal heart rate, with the same warm-up and cool-down, 50 minutes in all. Peak oxygen uptake rose 19% in both groups.⁶ It was a small trial, of 9 and 10 men, and "all-out" there meant all-out.

A beginner's version builds up to that:

"Hard" means you could get out a few words, not a sentence. Turn the resistance up for the hard part rather than just spinning faster, and back down for the easy part. One interval ride a week is plenty for a beginner; the rest steady.

A four-week beginner plan

After week four, keep adding five minutes to the steady rides every week or two until they're the length you want, and move up the interval stages one at a time. If a week goes badly, repeat it rather than skipping ahead.

What indoor cycling did in the studies

A 2019 systematic review gathered 13 studies of indoor cycling, with 372 participants, 306 of them women. Programs ran 8 to 24 weeks, with two to six sessions a week of 30 to 100 minutes. Two to three sessions a week improved maximal oxygen uptake by 8 to 10.5%. The review's caveat matters: only one of the 13 was a randomized controlled trial, so the authors say the conclusions should be taken with caution.⁷

The stationary bike for weight loss

Here's what the trials measured, without spin:

• Body weight. In the 2019 review, nine studies measured body mass, and none reported a significant improvement compared with a control group. Seven measured body fat: all seven found it fell within the cycling group, and two found the drop significant against the comparison group.⁷
• Cycling with diet. The same review recommends combining indoor cycling with diet to lose weight.⁷
• The bike asks for less energy than some machines. At the same rated effort, the bikes came in below the treadmill, the stair climber and the elliptical in the seven-machine study.¹ That's the trade for sitting down.

So the bike is a good way to get your cardio minutes, and a small lever on the scale by itself. The bigger levers, daily steps and what you eat, are on walking for fat loss, and how intervals and steady rides compare for body fat is on HIIT vs steady-state cardio.

The bike beside lifting

For people who lift, the bike has one point in its favor. In a small nine-week trial of 30 untrained 18-to-23-year-olds lifting twice a week, adding cycling left leg-press gains below lifting alone, as adding incline treadmill walking did, but the men who cycled gained more strength than the men who walked; the authors suggest cycling is closer to the movement of a leg press or squat.⁸ Ride after lifting or on another day, and keep the hard interval ride away from the day before leg day. Cardio and lifting covers the order and the timing.

Common questions

How long should a beginner ride a stationary bike?

Fifteen to twenty minutes for the first week, building to 30. Twenty minutes three times a week is a solid start, and the WHO's guidelines say some activity is better than none.⁵

Is 30 minutes on a stationary bike a good workout?

Yes. At a moderate pace, five of them is 150 minutes, the low end of the WHO's weekly range.⁵

Spin bike or recumbent bike for a beginner?

Either. The recumbent has a back rest and is the easiest to get on and off; the spin bike asks more at the same effort.¹ If your back or knees hurt on a bike, see a doctor or a physical therapist.

Does a stationary bike build leg muscle?

It isn't how the studies above measured it. For bigger, stronger legs, lifting is the tool: a leg day workout is the place to start.

If you'd rather have the rides planned for you

A bike plan is easy to write; fitting three rides, a few lifting sessions and the way you eat into one week is the part that falls apart. If fat loss is the goal, that's the job I take on in coaching: the training lives in the Trainerize app, we talk through the week on a call, and I rework the next one from what actually happened. Fat loss coaching lays out how, and applying is the first step. Or just start: two steady rides this week, twenty minutes each, at a pace you can talk through.
