Boxing vs Spinning
Two of the most popular group fitness classes in London. Both will leave you drenched in sweat. But one builds a skill that lasts a lifetime, and the other is, at its core, a stationary bicycle with music and lighting. Here is the honest comparison that the boutique studios would rather you did not read.
The Core Difference
Boxing
A full-body, skill-based discipline with unlimited technical depth. Every session is different.
- • Full-body: arms, shoulders, core, legs
- • Complex skill with years of progression
- • Varied movements every session
- • Builds confidence and self-defence
- • Social partner work (pads, sparring)
Spinning
Lower-body cardiovascular training on a stationary bike. Studio atmosphere compensates for movement simplicity.
- • Primarily legs: quads, hamstrings, glutes, calves
- • Single repeated movement pattern
- • Music, lighting, and instructor energy
- • Low barrier to entry
- • Low impact on joints
Boxing asks you to learn. Every session involves technique, combination work, footwork, timing, and defensive movement. After a year, you are still discovering new layers. Spinning asks you to pedal faster or slower, with more or less resistance. The movement never changes. Studios compensate with loud music, dramatic lighting, and charismatic instructors, but the underlying activity remains identical from your first class to your five-hundredth.
This distinction matters enormously for long-term adherence. Many people enjoy spinning intensely for six months to a year, then quietly stop going. Boxing's technical depth keeps people engaged for decades.
Calorie Burn: The Numbers

Boxing has a clear calorie advantage. A typical boxing training session burns 20-40% more calories than a typical spinning class. The difference comes from full-body engagement: boxing works your arms, shoulders, core, and legs simultaneously, while spinning primarily works your legs with minimal upper body involvement.
Some spinning studios market calorie burns of 700-1,000 per class. Be sceptical. Those numbers typically come from heart rate monitors that overestimate calorie burn in heat-stressed environments (like the deliberately warm studios many spin chains use). Independent research consistently places spinning calorie burn lower than boxing.
Full Body vs Lower Body
Boxing is a genuine full-body workout. Every punch engages your core, shoulders, arms, and legs. Add in defensive movement, footwork drills, and conditioning circuits, and there is no major muscle group left untouched. Over time, boxing builds lean, defined muscle across your entire body.
Spinning is almost exclusively a lower-body workout. Your quads, hamstrings, glutes, and calves do the work. Your upper body sits relatively idle, gripping the handlebars. Some instructors incorporate light dumbbell segments, but using 1-2 kg weights while pedalling is negligible for muscle development. If spinning is your only exercise, you will develop a significant imbalance between your lower and upper body.
This is not a minor point. Upper body strength matters for daily life, posture, bone density, and metabolic health. An exercise that only trains half your body requires supplementary training for the other half. Boxing does not have this problem.
Injury Risk and Long-Term Effects
Spinning is low-impact and low-risk for acute injury. The main concerns are overuse injuries from repetitive pedalling: knee pain (particularly patellofemoral syndrome), hip flexor tightness from the constant flexion position, and postural effects from spending 45-60 minutes hunched over handlebars. Saddle discomfort is also a genuine issue that regular spinners learn to tolerate rather than solve.
Boxing (non-sparring) is also low-risk. Minor wrist and hand strains are the most common issues, largely preventable with proper hand wrapping and coaching. The varied movement patterns of boxing actually reduce overuse risk compared to the single repetitive motion of spinning. At Honour and Glory, beginners are taught wrapping and technique from day one.
One factor people overlook: spinning offers zero bone density benefit. The non-weight-bearing, non-impact nature of cycling (indoor or outdoor) means it does not stimulate bone strengthening. Boxing, through impact and weight-bearing movement, does. This matters increasingly as you age, particularly for women.
Cost in London
London prices as of 2026. Boutique prices based on Psycle, 1Rebel, and Boom Cycle pricing.
Boutique spinning is expensive. Psycle charges £22 per class. 1Rebel and Boom Cycle are in a similar range. Monthly unlimited packages at premium studios exceed £150. A Refinery29 review of SoulCycle London noted that class packs cost "an eye-watering £180." For a workout that involves pedalling a stationary bike, that is a lot of money.
Community boxing clubs charge £5-£10 per session with no contracts. You can train boxing four times a week for an entire month for less than the cost of eight spinning classes at a boutique studio. The value comparison is not even close.
Who Each One Suits
Boxing suits you if: you want higher calorie burn, full-body muscle development, and a skill that lasts a lifetime. If you want better value for money. If you enjoy varied, technically challenging training that keeps you mentally engaged. If confidence, stress relief, and the ability to defend yourself appeal to you.
Spinning suits you if: you specifically enjoy cycling and the studio atmosphere. If you want the absolute lowest-impact option for your joints. If you prefer a workout where you can switch off mentally and follow the instructor's cues and the music. If convenience and class availability matter more than variety or skill development.
The Crossover: Where Spinning Adds Value
In fairness to spinning, it does serve a purpose alongside boxing. The sustained cardiovascular effort of a 45-minute spin builds aerobic base fitness that improves boxing endurance. The zero-impact nature makes it a decent active recovery option between hard boxing sessions. And the lower-body conditioning transfers directly to boxing footwork and stance stability.
If you can access spinning cheaply through a gym membership you already have, one spin session per week alongside two or three boxing sessions is a reasonable programme. The spinning builds base cardio. The boxing provides everything else: skill, full-body strength, core power, confidence, and community.
What makes less sense is paying boutique prices for spinning when community boxing gives you a more complete workout for a fraction of the cost. If budget is limited, boxing alone is the stronger choice every time.

Which Should You Choose?
Choose boxing if:
- • You want higher calorie burn per session
- • Full-body muscle development matters
- • You want to learn a genuine skill
- • Budget matters (£5-£10 vs £15-£25 per class)
- • You want variety and mental engagement
- • Confidence and stress relief are important
Choose spinning if:
- • You specifically love cycling as an activity
- • You want the absolute lowest joint impact
- • You prefer to follow music and cues, not technique
- • Studio atmosphere matters more than skill
- • You want a simple, low-barrier workout
- • You already have an unlimited gym membership
Our honest take: For most people, boxing is the better workout. More calories, more muscle groups, more skill, more engagement, dramatically lower cost. Spinning is a decent cardiovascular session, but it is a one-dimensional exercise at a premium price.
We are a boxing gym, so take that with appropriate context. But we see former spinning regulars walk through our door frequently, and the feedback is consistent: the training is just as intense, the community is stronger, the skill element keeps them engaged, and they are spending a fraction of what they were paying at the studio.
