Warm-ups are a critical component of any workout routine, especially for those engaged in strength training. However, the efficacy and structure of warm-ups have often been subject to debate among fitness enthusiasts and professionals alike. Many lifters dedicate extensive time to warm-ups, incorporating various exercises and modalities, with the belief that skipping any part of this ritual may compromise their performance and gains.
This article delves into the scientific literature on warm-ups, particularly focusing on their impact on lifting performance and strength outcomes as explained by Dr Pak Androulakis-Korakakis.

The Perfect Warm-Up For Muscle Growth and Strength
Warm-ups generally fall into two categories: general and specific. A general warm-up typically involves aerobic activities designed to increase muscle temperature and heart rate, such as walking on a treadmill or cycling at moderate intensity. Specific warm-ups, on the other hand, involve performing the actual exercises planned for the workout, starting with lighter loads and gradually increasing intensity.
A narrative review published in 2021 explored the existing literature on the subject, highlighting that while more research is needed, current evidence suggests a combination of both general and specific warm-ups may be most beneficial for lifting performance. The review indicated that a general warm-up followed by a specific warm-up involving progressively heavier loads tends to yield better one-repetition maximum (1RM) strength outcomes compared to specific warm-ups alone.
Scientific Insights: Key Studies on Warm-Ups
- General and Specific Warm-Up Study: A crossover design study involving 13 resistance-trained males compared the effects of a general plus specific warm-up versus a specific warm-up alone on leg press 1RM strength. Participants in the general warm-up group cycled for 20 minutes at 60% of their maximum heart rate, followed by specific warm-up sets at 50% and 70% of their 1RM. The specific warm-up group performed only the warm-up sets without prior cycling. The results showed that the combined warm-up group exhibited 8% greater 1RM values, suggesting that increasing muscle temperature through a general warm-up could enhance strength performance.
- Ribero et al. (2020): Another study examined different warm-up protocols for squats and bench presses. It compared light and heavy warm-ups, including two sets of six reps at 40% and 80% of 1RM, against protocols involving just one set of six reps at either 40% or 80%. Findings suggested that heavier warm-ups tended to improve performance more than lighter ones. However, it’s important to note that typical gym warm-ups often involve multiple lighter sets, which might also serve as a form of general warm-up.
Practical Takeaways
Based on current evidence, incorporating a brief general warm-up followed by a progressively intense specific warm-up is a safe and potentially more effective strategy for strength training. Here’s a recommended approach:
- General Warm-Up:
- Engage in 5-10 minutes of moderate aerobic activity such as brisk walking, light jogging, or cycling.
- Alternatively, dynamic stretching or performing additional sets of the workout exercise with very light loads can also serve this purpose.
- Specific Warm-Up:
- Perform the planned exercise starting with an empty bar or very light weight.
- Gradually increase the load over 3-5 sets until reaching the desired working weight.
- Example for squats: Start with bodyweight squats, then use an empty bar for 10 reps, followed by incremental weight increases (e.g., 40%, 60%, 80% of 1RM) for 5-8 reps each.
Injury Prevention and Warm-Ups
Many lifters believe warm-ups are crucial for injury prevention. While some studies, such as a 2015 review, found limited direct evidence linking warm-ups to reduced injury risk in lifting, the overall consensus is that a well-structured warm-up can help prepare the body for intense activity, potentially mitigating some injury risks. Engaging in strength training itself has been shown to be protective against injuries, further supporting the importance of regular, structured exercise routines.
Warm-ups are a vital aspect of strength training, with scientific evidence supporting the use of both general and specific warm-ups to enhance performance. While the exact structure may vary based on individual preferences and specific workout routines, incorporating these elements can help ensure optimal preparation and potentially improve lifting outcomes. Always listen to your body and adjust your warm-up routine to fit your needs, ensuring both safety and effectiveness in your strength training endeavours.
