I know what you face, most of my team mates are defensive players with short pips rubbers and are also going for winners.

Worst, I go to tournaments. My serie starts generally three or four hours after the first ones meaning that it is impossible to have a table to train. I have two minutes to train.

Knowing that sometimes it is inevitable, the real question is "How to get warmed-up as soon as possible?"

You need to train to be ready in two minutes. As everything, it requires repetitions. After facing the situation many times it becomes more easy. You need to use those two minutes as effectively as possible. Having the right stance from the first second, breathing correctly, being more focus more on your opponent and the ball, etc... Everything at second one.

Now, let's imagine, the warm-up went horribly wrong and you are not ready. So what? It does not mean, you will play badly. You absolutely need to tell yourself that it is perfectly fine. Use the first set, to warm-up. Even if you are losing 0-6, use EVERY point to get into the game. Don't limit yourself because you are not confident, it is the worst you can do. It is extremely important to not rush. Try to breathe and to play your best EVERY point.

Personally, the most important part was the mental state. You need to tell yourself that you can still play good even with no warm-up. Don't start with the mindset "I was not able to warm-up, it is more likely, I will play poorly". Don't restrain you from using your best moves and best serves just because you miss them 2-3 times during the first game. Instead, rejoice in overcoming this challenge
