Endurance training does not compromise gains in aerobic capacity when performed concurrently with resistance training.
You do not need to choose between getting fit (aerobic) and getting strong. You can improve your VO2max and your strength at the same time without one cancelling out the other.
GoodSupportsHIGH confidence
Of note is training-induced gains in aerobic capacity are not compromised by concurrent strength and endurance training.
Why this rating
Stated as a clear finding from concurrent training studies.

More from this paper
- Concurrent endurance and resistance training attenuates gains in muscle hypertrophy and strength compared to resistance training alone, a phenomenon termed the 'interference effect'.Good
- The molecular signaling responses to acute resistance and endurance exercise are often similar in untrained or recreationally active individuals, suggesting the interference effect may be less pronounced or mechanistically distinct in this population.Moderate

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
