Does boxing count as cardio or strength?
Mostly cardio, and hard cardio at that, with power on top. A review of amateur boxing by Chaabène and colleagues found that boxers of both sexes need a high level of cardiorespiratory fitness, both to meet the demands of a bout and to recover between rounds. It also found that high-level boxing needs well-developed strength and power in the legs as well as the arms. A punch is a brief, explosive action; the engine is what lets you keep throwing them round after round.
So a boxing night is already a conditioning session. Skipping, shadow boxing, pads, bag rounds and sparring all run in rounds with short rests. What the gym can give a boxer that boxing does not is heavy strength and fast power. It does not need to add another hard circuit on top. Our view: count each boxing night as one of the hard days in your week, and let your lifting sessions do the job boxing cannot.
A boxing-style fitness class, with pads or a bag and no sparring, is a different thing: a class someone else has programmed rather than the sport, and gym classes rates the common ones by what they measurably do. This page is about boxing in a gym that spars.
Lift before or after boxing?
On a different day if you can, and hours apart if you cannot. The best evidence on combining the two comes from conditioning and lifting in general, not from boxing, and it says something specific about which quality is at risk.
- Maximal strength and muscle size held up. Across 43 studies of healthy adults pooled by Schumann and colleagues, people who added conditioning to their lifting built as much maximal strength and muscle as people who only lifted.
- Explosive strength did not. Its gains were smaller, significantly so where the conditioning and the lifting came within 20 minutes of each other, in either order. Where they were 3 hours or more apart, the difference was not significant.
- Power is the quality to protect. A second meta-analysis, by Huiberts and colleagues (59 studies, 1,346 adults aged 18 to 50), found interference for power in both sexes, a small one for lower-body strength in men but not in women, and none for upper-body strength.
Neither analysis studied boxing. Schumann's studies used cycling, running and, in one case, rowing, and Huiberts notes that most of the studies recruited relatively untrained people. None of them tested punching or sparring. Treat these as the closest evidence there is, not a boxing rule. The direction is still clear: power, the quality a punch depends on, suffers in both analyses, and sharing a session is where it suffers most. The science behind that is set out in more depth in running and lifting.
Put the sessions hours apart: lift in the morning and box in the evening, or the other way round. One of the boxing trials below ran its strength and power sessions in the morning, with boxing that evening, and punch power still rose. If one session has to come second, our view is that sparring deserves the fresher you. A technique session copes better with tired legs than sparring does.
Stop sets well short of grinding. In a trial of 10 resistance-trained men, Morán-Navarro and colleagues compared squats and bench press taken to failure with sets stopped at half the reps the men could do. Sets to failure left jump height, bar speed and blood markers slower to recover, with the difference lasting 24 to 48 hours. The authors' point was practical: avoiding failure leaves athletes in better condition for the next session. For a boxer, the next session is usually a boxing night.
Where does power work go in a boxing week?
Fresh, and away from sparring. Power work means jumps, medicine-ball throws and fast lifts: short, maximal efforts where speed is the whole point. It trains the quality concurrent training blunts, and a power set done tired turns into conditioning. Our view: do it early in a lifting session, after the warm-up and before anything heavy, on a day when you have not boxed hard in the hours before.
Two recent trials in boxers give a sense of what that work can do:
- Pinto and colleagues followed 31 male club boxers through eight weeks (45 started). All followed the same boxing programme; two groups added strength and power work aimed at straight punches or at hooks. Punch power rose overall, the boxing-only group gained least (its lead hook did not improve), and the rotational group improved most, especially on hooks.
- Han and colleagues had 28 male collegiate boxers, in season, do lower-body lifting for eight weeks. Ending each set once bar speed dropped 10%, with live feedback, gave greater mean gains in straight-punch force and in 10 and 30 second punch counts than fixed sets of five at 70% of one-rep max. The velocity group's loads were also set by bar speed, and the authors credit the whole package, not the stopping rule alone. Over one minute there was no clear difference, and the authors call the punch results exploratory, not a recommendation.
Neither trial is large, both measured young men from a single club or university, and neither programme is one to copy. In both, average punch measures went up, not down, in the groups that lifted. Han's authors read their result as consistent with the possibility that regulating sets by bar speed may be particularly relevant where performance depends on rapid, forceful actions, and they say it is not yet a reason to recommend the method routinely. For what the gym should add for a striker, and why, see martial arts strength training.
Where do boxers get hurt?
Mostly in the arms and hands, in training. A meta-analysis of 17 cohort studies of amateur boxers found the upper limb accounted for a median 49% of training injuries, and in five years of records from the 66 boxers who passed through the Great Britain squad, the hand was injured more than any other part of the body, in training and in competition, and the authors concluded that prevention should aim to protect the hands and wrists. If a hand, wrist or shoulder hurts, or keeps hurting after sessions, see a physio or doctor, and keep heavy loading off it until you know what it is.
The sample week below leans on legs and pulling rather than heavy pressing, because punching is already a pushing action, repeated in every session. That is our view of a sensible balance, not a tested way to prevent injury.
Kickboxing and Muay Thai
Everything above applies, with one difference: the legs strike too. Kicks and knees put the hips and legs to work in every round, so in kickboxing and Muay Thai the lower body is both the engine and a weapon. Huiberts found interference for power in both sexes and for lower-body strength in men, and in our view a kick depends on both.
Our view: if you kick, keep heavy leg sessions and jumps away from sparring nights as well, not only the upper-body work. In the sample week, the Monday leg session already sits two full days before Thursday's sparring. The trials on this page measured boxers, so for kicking styles they are a guide rather than proof.
MMA adds grappling to striking. For the grappling side, and for keeping heavy pulling off rolling nights, see BJJ and lifting.
A sample boxing week
Here is how the evidence fits around three boxing sessions, one of them sparring. Power comes first in a session and on a day without boxing. Lower-body strength and pulling go on days without boxing. Every lifting set stops with reps to spare. There is an easy day after sparring and a rest day with nothing on it.
| Day | Boxing | Gym | Why |
|---|---|---|---|
| Mon | None | Power first (jumps or medicine-ball throws), then lower-body strength: a squat or split squat and a hinge. Every set stopped with reps to spare. | Power done fresh, with no boxing in the same session (Schumann); sets stopped short (Han, Morán-Navarro). |
| Tue | Evening: technique, pads, bag | None | A boxing night is already hard conditioning (Chaabène). |
| Wed | None | Pulling and upper back: rows, pull-ups or pulldowns. Sets stopped short. | Upper-body strength held up under concurrent training (Huiberts). Pulling rather than heavy pressing, because punching is already a pushing action repeated every session (our view, not a tested way to prevent injury). |
| Thu | Evening: sparring | None | The night to be sharpest, so nothing heavy or explosive earlier that day (our view). |
| Fri | None | Easy day: a walk, easy cycling or mobility. | Easy, not hard, after sparring (our view). |
| Sat | Bag rounds and conditioning | None | The third boxing session, with nothing heavy beside it. |
| Sun | None | Rest: nothing at all. | A rest day has nothing on it (our view). |

Add boxing under You: in SPORTS STACK, tap + ADD. Boxing, kickboxing and MMA are in the list. Muay Thai goes in as Kickboxing: search for it, or type it under Other. With Pro or during your trial, your coach then plans your strength and conditioning around what you already do instead of on top of it. More in Add a sport or a class.
On the sport's settings, choose Fixed days if your gym runs a timetable, where each day you pick is one session a week, or Flexible to let the app pick the days around your other sports and classes. Set your usual session length too. At the top of that screen is a line about what the sport does to your body; with Pro or during your trial, that is what your coach is working around. If your sparring night changes for good, change the days there; with Pro or during your trial, saving rebuilds your plan around the new shape of your week. More in Sport settings.
If a hand, wrist or shoulder flares up, report it from LIMITATIONS on Home and set how serious it is, from Cleared to Serious. With Pro or during your trial, your plan is rebuilt around what you report. Your coach is a training tool, not a medical service, and it tells you to see a physio or a doctor.
