Boxing workout: a non-contact session in rounds, and what it does for you

What a boxing workout involves

Fitness boxing borrows the training of boxers without the fighting. A session usually mixes:

• Shadowboxing: punching the air in front of a mirror, to learn the movements.
• Bag work: punching a heavy bag in timed rounds.
• Pad work: a partner or coach holds pads and calls combinations.
• Footwork and conditioning: moving around the bag, skipping, squats, push-ups and core work.

Training is organised in rounds, traditionally three minutes of work and one minute of rest. That structure makes it an interval session, like the formats in our guide to short, hard workouts.

How intense it is, and what the evidence says

The 2024 Compendium of Physical Activities gives these values:

• Punching bag, general: 5.8 METs.
• Punching bag at 60 punches a minute: 7.0 METs; at 120: 8.5 METs; at 180: 10.8 METs.
• Simulated boxing round, as exercise: 9.3 METs.
• Kickboxing: 7.3 METs.

The World Health Organization counts 6 METs or more as vigorous, and accepts 75 minutes of vigorous activity a week in place of 150 minutes of moderate activity. A well-paced boxing class therefore counts at the higher rate.

The NHS lists martial arts among vigorous activities, and among aerobic exercises that, done hard, also strengthen muscles. On mood, Bozdarov and colleagues reviewed 16 documents on non-contact boxing and reported reductions in anxiety, depression and post-traumatic stress symptoms, with improved mood, confidence and coordination. They describe the evidence as promising but preliminary, and call for proper randomised trials. Boxing is not a treatment, but many people find hitting a bag an effective way to reduce stress after a long day.

A first session of 36 minutes

The calculator below adds up the rounds, the rests, the warm-up and the cool-down.

1. Warm-up, 8 minutes: easy skipping or marching on the spot, arm circles, then light shadowboxing.
2. Rounds 1 and 2, 3 minutes each: jab and cross on the bag, moving your feet between combinations. One minute of rest after every round.
3. Rounds 3 and 4: add hooks, and work in bursts of 20 seconds fast, 10 seconds steady.
4. Round 5: a bodyweight circuit of squats, push-ups and plank, 30 seconds each, repeated.
5. Round 6: free combinations, at a pace you can hold until the bell.
6. Cool-down, 5 minutes: slow walking, then stretches for the shoulders, chest and hips.

If three minutes is too long at first, start with rounds of two minutes and one minute of rest, then lengthen them over the following weeks. A jump rope workout makes an excellent warm-up and a conditioning round.

The basics of technique

• Stance: feet shoulder-width apart, the lead foot forward, knees soft, weight on the balls of the feet.
• Guard: hands up by the cheeks, elbows in, chin slightly lowered.
• Jab: a straight punch with the lead hand, returned straight to the guard.
• Cross: a straight punch with the rear hand, turning the rear hip and foot.
• Hook: a short, bent-arm punch from the side, turning the body rather than swinging the arm.
• Breathing: breathe out sharply with each punch, never hold your breath.

Power comes from the legs and hips. Punch at about three-quarters of your strength while you learn, and keep your wrist straight on impact.

How often to train

Three sessions like the one above give 54 minutes of rounds at vigorous intensity; a fourth session, or a few brisk walks, completes the World Health Organization's weekly guideline. When you start, leave a rest day between sessions. Keep at least one session of full-body strength work as well, since boxing loads the legs and back less than squats or deadlifts do. See how much exercise per week.

Precautions

• Protect your hands. Wear hand wraps and properly fitted gloves for bag work, never punch a heavy bag bare-handed, and keep the wrist straight on impact.
• No sparring without supervision. In competitive boxing, a 2023 meta-analysis by Mao and colleagues found that concussions made up about 12% of recorded injuries, and soft tissue bruising was the most common type. Fitness boxing avoids head contact altogether; keep it that way unless you join a properly coached club.
• Respect your shoulders. Do not lock the elbow on straight punches, and build up the number of rounds gradually.

If you have a heart condition, high blood pressure, a recent injury to the hand, wrist or shoulder, or have been inactive for a long time, talk to your doctor before starting a vigorous class. Stop if you feel chest pain, dizziness or unusual breathlessness.

Keep your rounds going with a crew on Never Skip Club

A boxing class works best when it is one fixed part of a week you keep. Create your free account, build a guided strength session in a minute for the other days, and start a crew with friends: a session of 30 minutes or more counts, and the ranking rewards regularity rather than extra sessions. If you want pads held by someone who knows technique, find a coach from our network, or sign in if you already have an account.
