Spinning: A study by the American Council On Exercise found spinners worked at 75-96 % of their maximum heart rate – far exceeding the minimum requirement.
Cycling: Not quite as good as spinning . Still, research shows the average amount of oxygen the body can take in and use each minute is 73.5ml/kg in pro-cyclists – compared with 42ml/kg in non-cyclists.
Spinning: The fact that there’s no respite in spinning – no change of scenery, say – can make spinning “feel” harder than cycling outdoors. However, the music and group motivation can help to off set this.
Cycling: The varied intensity of outdoor riding – freewheeling, uphill inclines, etc – can make it feel much more satisfying and spontaneous than fi xed cycling in a closed environment.
Spinning: Once you get to the gym, you can work at your own personal level, while still being part of a group – in a dry, temperature-controlled and safe environment.
Cycling: Since you can cover a lot of miles in an hour, you need to plan your routes – and watch the weather. There’s also an inherent risk from being on the road . And, if you do get hooked, cycling can be expensive.
Spinning: Spinning uses the same muscles as road biking. However, the weight of the fl ywheel ( 14-18kg) increases the number of pedal strokes per minute, forcing the hamstrings to work harder.
Cycling: Cycling uses all the major lower-body muscles – the glutes, hamstrings, quads, shins and calves. The thighs, in particular, are worked incredibly hard.
Spinning: The fixed wheel of a spinning bike means you can’t “freewheel” – so your muscles work the whole time. This makes it a pretty high-intensity activity, burning a lot of calories.
Cycling: Cycling has the potential for high-energy expenditure – particularly when you’re covering high mileage or taking in hilly terrain. The average Tour de France rider burns 124,000 calories during the race.
