How to Warm Up Before Training

I've been going to the gym recently and I usually start lifting as soon as I reach. Someone told me that warming up properly can help prepare the body for exercise. What kind of warm up do beginners usually follow before starting their workout?

Start with 5 minutes of light walking or cycling

Do some arm circles and shoulder movements

Warm up the muscles you're planning to train

try a few light sets before your working sets

You don't need a very long warm up

Avoid jumping straight into heavy weights

Dynamic movements are useful before training

Make warming up a regular part of your routine
