Cardio Before or After Weights?
General information: This article is general information about combining cardio and strength training and how an app works. It has not been reviewed by a dietitian, doctor or qualified trainer, and it is not a substitute for their advice.
In an Indian gym the treadmill is often available first and the squat rack is busy, so people do cardio first and weights after. Others swear by lifting first. This page checks what meta-analyses of combining cardio and strength training report about order, then gives a simple rule.
The short answer
Doing both is fine for muscle size and maximal strength. A meta-analysis of 43 studies (Schumann et al., 2022) found that adding aerobic training to strength training did not compromise muscle growth or maximal strength. If lifting is your priority, put the weights first: two meta-analyses of training order found a possible advantage for lower-body strength when strength training came before endurance in the same session, and no difference in aerobic capacity.
What the research says
- Combining both does not blunt size or maximal strength. The meta-analysis of 43 studies (Schumann et al., 2022) of healthy adults compared strength training alone with strength plus aerobic training. It found no significant effect on maximal strength or muscle hypertrophy, but explosive strength may be attenuated, especially when both are done in the same session rather than at least 3 hours apart.
- Weights first: higher lower-body strength in one review. The meta-analysis of training order (Murlasits et al., 2018) compared strength-then-endurance with endurance-then-strength in the same session. Lower-body 1RM was higher, by a pooled 3.96 kg (95% CI 0.81 to 7.10), when strength came first, and the order did not change aerobic capacity.
- A second review agrees. The review of 10 studies (Eddens et al., 2018) found a resistance-then-endurance order gave a 6.91% greater change in lower-body dynamic strength, with no effect of order on lower-body muscle size or aerobic capacity.
These are reviews of training trials, not observational surveys. They pooled a small number of studies (10 in one of the order reviews), mostly measured lower-body strength, and their confidence intervals are wide (the lower ends were 0.81 kg and 1.96%), so the advantage could be very small. They describe averages in healthy adults, not what will happen to you.
A simple rule (our practical template)
The table below is our own reading of those reviews, not a trial result.
| Your priority | A sensible order |
|---|---|
| Strength or muscle is the goal | Weights first, then a short cardio finisher if you want one. |
| A long run or ride is the goal that day | Do it first, or on a separate day, and keep the weights short. |
| Only the treadmill is available | Use it as a short warm-up (see how to warm up), then lift. |
| You can split the day | Separate sessions by at least 3 hours, as in the 43-study review. |
Plan the week around frequency first: a strength plan like the beginner gym plan, plus cardio on other days, and see how many days a week you can keep up. Give yourself enough rest between sets so tiredness from cardio does not shorten your lifting.
When to ask a doctor or trainer first
If you have an injury, pain, a heart condition or another medical condition, are pregnant, or have not exercised for a long time, ask your doctor or a qualified trainer before you combine hard cardio with weights. Stop and get advice if you feel chest pain, dizziness or sharp pain.
Tracking both in NYUS
NYUS is an AI diet and workout coach. On the workout screen you can log each set and use the rest timer, and each exercise shows what you did last time ("Last: ..."). The Activity screen shows your steps against your step goal, and steps can sync from Health Connect. NYUS does not decide the order of your cardio and weights: that is yours to choose.

Should I do cardio before or after weights?
If strength or muscle is your priority, our practical reading is weights first. Two meta-analyses of training order found lower-body strength was higher when strength came before endurance in the same session, with no difference in aerobic capacity. A 43-study meta-analysis found adding aerobic training did not compromise muscle growth or maximal strength.
Does cardio hurt muscle gain?
A meta-analysis of 43 studies found that concurrent aerobic and strength training did not compromise muscle hypertrophy or maximal strength compared with strength training alone. Explosive strength may be attenuated, especially when both are done in the same session.
Is it better to do cardio on a separate day?
The 43-study meta-analysis found the attenuation of explosive strength was more pronounced when concurrent training was done in the same session than when sessions were separated by at least 3 hours. Overall, maximal strength and muscle size were not compromised.
Can I use the treadmill as a warm-up?
Our practical reading is yes: a few minutes of easy cardio is a reasonable start before lifting. Longer or harder cardio is better placed after the weights if lifting is your priority.
