Hi Jaydee. Welcome!
There is a specific section in the Darebee webpage that covers exactly what you might be looking for:
Warmup and Stretching (click in this link to see it).
Yes, (long story short) science would suggest it is essentially compulsory, especially as adults, and as we age.
It is important in order to avoid strains, injuries, pulls and pain.
Think of your body like an second hand car on a cold morning—you need to let the engine "idle" for a bit before you hit the highway.
Ideally, for about 5 to 10 minutes, do gentle, continuous movements like marching in place, slow walking, or arm circles until you feel a light sweat, or perform gentle movements that involve the same body areas you plan to work on. This gradually prepares your heart and "greases" your joints with natural fluid, which makes your workout feel easier and protects you from sudden pulls or strains.
If the idea of warming up for so long would deter you from exercising, perhaps try any of the following darebee curated warm-ups.
Some of them take 1-2 minutes and will prime your joints, muscles and neural network:
Universal warmup
Quick Warmup
Classic Warmup
2 minute Warmup
4 minute Warmup
Fighter's Warmup
Alternatively, you could try some
youtube/online videos that show you how to do it, and have their own version of warmups.
I look forward to other people's view on this, as there isn't really a consensus on what is "the best" warmup.
In
Body Lifting, warming up would involve lifting light weights before jumping to the bigger ones you'd plan to do the sets with.
In
different martial arts, the warmup can also look very different. For example in
Aikido there is a strong focus on tendons, flexibility and range of movement.
If it's your jam, you could also look for
qigong warmup videos, although those tend to last
10-20 minutes, and could be considered light workouts on themselves.
But if you prefer something meaningful that also provides a bit of
meditation/relaxation/automassage, it is a fantastic warmup or active rest activity.
Let me know if this resonates with you!
All the best.
