We’ve probably all skipped a warmup before we’ve dived into a workout, right? We may have even reasoned with avoiding it because we’ll ‘warm up during exercise’, or ‘it’s just a pre-workout before my workout so what’s the point?’.
Warm-ups prepare your muscles for activity
Warmups help avoid injuries

Your warmup depends on your workout
Warm-ups aren’t a ‘one size fits all’ approach to exercising at peak performance. Afterall, there are around 640 skeletal muscles in the average human body, organised into major groups, each responsible for their own area. Unless you’re some kind of superhero, you’re probably not going to use all of them in your workout.
Different workouts with different intensities call for different warmups. For example, runners focus on warming up areas such as the hamstrings and quadriceps, while upper body workout warmups will need to target pectorals, trapezius, triceps, and biceps.
Stretching - Dynamic vs Static
Dynamic stretching (jogging on the spot, bodyweight squats etc.) are perfect for warming up because it helps the muscles reach their full range of motion in a way that is functional and constantly active while increasing blood flow to help gear them up for action. Static stretching (long holds in the same stretched position) are ideal as a post-workout cooldown, but as a warmup, they allow the muscles to lengthen but not contract, meaning they’re not getting the full range of motion they need.
