A proper warm up is essential to any workout, but it’s often the first thing to fall by the wayside. Whether you’re heading out for a run, lifting weights, or joining a Pilates class, how you prepare your body beforehand can have a major impact on your performance, injury risk, and recovery time. But not all warm-ups are created equal. Different forms of exercise require different strategies, and understanding the purpose behind each approach is key to getting it right.

Why warming up matters
Warming up isn’t just about breaking a sweat. A well-structured warm-up gradually raises your heart rate, increases blood flow to your muscles, and primes your nervous system for the movements ahead. It also helps to improve flexibility, reduce the risk of strains and sprains, and mentally prepare you for the session. Skipping it can leave your muscles cold and tight, making them more prone to injury and reducing your ability to move efficiently.
Cardio warm-ups: build gradually
If you’re preparing for cardio-based activities such as running, cycling, or swimming, the aim is to gradually elevate your heart rate while activating the muscles you’ll be using. Start with gentle, full-body movement—brisk walking, light jogging, or slow pedalling—and build the intensity over 5 to 10 minutes. This allows your cardiovascular system to adjust and helps loosen stiff joints, especially if you’re exercising in cooler weather or after a long day of sitting.
Dynamic stretching, think leg swings, arm circles, and lunges with a twist, can be helpful here, especially if it mimics the movement patterns of your chosen activity. Avoid static stretching before cardio, as holding stretches can reduce muscle power and don’t actively prepare the body for motion.
Strength training warm-ups: activate and mobilise
Resistance training aims to prepare your joints and muscles for the loads you’re about to lift. Begin with mobility drills that target the areas you’ll be working on, for example, hip openers and shoulder rolls if you’re doing a full-body workout. From there, progress to lighter sets of your planned exercises using reduced weight. This gets your muscles firing and reinforces good technique and range of motion.
Incorporating resistance bands or bodyweight movements such as squats, lunges, and push-ups can be a great way to activate the muscles you’ll be using without placing undue stress on them. A thorough warm-up here can also help you lift more effectively and recover quickly afterwards.
Yoga and Pilates: focus on breath and flow
Although yoga and Pilates are often gentle workouts, they still benefit from a specific warm-up. Begin with breath-led movement to engage your core and bring awareness to your posture. In yoga, this might mean starting with cat-cow stretches, seated twists or gentle sun salutations to wake up the spine. In Pilates, slower sequences like pelvic tilts and shoulder bridges are helpful in activating deep core muscles and easing into your practice.
These sessions rely heavily on control and alignment, so your warm-up should be mindful and focused. Rather than ramping up intensity, the aim is to create a strong foundation for movement and prevent overcompensation or strain in more demanding poses or exercises.
Stretching after your workout
It’s a common misconception that stretching belongs at the start of every session. In reality, static stretching is more beneficial after your workout, when muscles are warm and pliable. This is the time to hold positions that lengthen the muscles, ease tightness and support flexibility over time. Stretching post-exercise can also help bring your heart rate down and signal your body that it’s time to recover.
One size doesn’t fit all
Ultimately, the right warm-up depends on what you’re preparing for. A few jumping jacks before lifting heavy weights won’t cut it, just as lifting light dumbbells won’t prepare you for a long-distance run. Tailoring your warm-up to your activity ensures you’re performing at your best and reducing your chances of injury in the long run.
So the next time you’re tempted to skip those first ten minutes, remember: warming up isn’t optional. It’s an essential part of training well and training smart.
