Imagine when you run, or cycle, you could see the results of your efforts instantly. How amazing it would be to literally see the fat on your stomach or bum melt away! How motivational!
Well this is what we experience every time we train with weights and get a pump. We can see the muscle grow, see our vascularity increase and generally witness what our muscle will look like in the future.
This is why, apart from the pleasurable feeling of a muscle engorged with blood, we love getting a pump!
We can see, immediately, what we will look like in the future!
Getting a pump is like a glimpse into the future!
