Depending on experience, it can be greatly benefitial in terms of exercising technique.
Although I have some experience in lifting weights, anytime I trained with a friend of mine who is a trainer he found lots of minor mistakes in technique I'm doing that cause muscular imbalance.
Of course, as mentioned above, it has to be a motivated professional. If your main concern is to overcome stagnation simply the right training partner could do the job.
I'd probably ask for a test session and go from there.
