How often have you skipped a warm up before a weights or resistance training session, simply because you:
a) Don’t know what to do;
b) Don’t have the time;
c) Don’t think it’s necessary; or
d) All of the above
If you can relate to any of those, you’ll want to read on.
Let’s start with the why; why do we need to warm up before a weights session?
We need to prepare our body for exercise by increasing our heart rate, loosening our joints and increasing blood flow and circulation. We need to perform a warm up prior to training to increase the blood flow to our muscles, which enhances the delivery of oxygen and nutrients, and promotes the energy releasing reactions used during exercise. Warming up also raises our muscle’s temperature (hence the term ‘warm up’) for optimal flexibility and efficiency.
So, does that mean we just need to do a few extra km’s on the treadmill?
Not necessarily, there are multiple ways to help our body prepare for a weights training session.
These aren’t just your average stretches – what we need to achieve with dynamic stretching is activation! Dynamic stretches mimic sports-like movements, prepare the body for activity and increase range of movement (ROM). Unlike static stretches, the end position of the stretch is not held therefore is felt further with each motion. Some examples of dynamic stretches include walking lunges, arm swings/circles, plank windmill/twist, toe touches, hip raises, high knees and bear crawls.
Joint Mobility Exercises
We’d all be lying if we said we didn’t want to jump higher, run faster and move without pain. All of this can be made possible by increasing our range of motion through joint mobility exercises. Increasing the flexibility in our muscles and tendons allow for a greater ROM. Joint mobility exercises are similar to that of dynamic stretching or stretching while moving through movement. Examples of these exercises include walking hip openers and thoracic spine windmills on the floor.
This is something that we do during our training, so think of it as a pre-exercise warm up – or a gradual increase in intensity during sets. In order for our muscles to grow we need to provide them with stressors to adapt to. Start with your bare minimum, whether it’s body weigh bench dips, squats using a barbell without weights or using the 4kg weights before hitting the heavier weights for your bent over rows. This will assist in preparing your body through the proper range of movement to achieve hypertrophy, strength, power and endurance.

Try to keep conditioning as your warm up to a minimum – after all, we want our weights to be the thing that takes up our strength and energy! Skipping, walking with gradual incline on a treadmill, step-ups or using the step machine should be kept to 2-5 minutes before training and are better kept for your HIIT sessions. If you find that you have some energy left after your training and before static stretching you can add your 2km row here. After all, it’s shampoo (exercise) and then conditioner.
Completing a warm up is essential for the time (and sweat) you are putting in to your weights training. Make sure to avoid static stretching (where you hold the stretch in one place for a few seconds) cold muscles before your session by opting for dynamic stretching. Spending 3 – 5 minutes before your training session to increase your blood flow will increase your range of motion, help decrease muscle stiffness and lower the risk of injury (see my 7 Trainer Approved Tips to Prevent Injury here!).
