I am having trouble with the white balance on Photoshop. Lots of yellow. Trying with the blue balance, etc. taking out the yellow. Still not right. Any suggestions will be appreciated.

It's obvious that if you had a gray card or a color checker in the photo, the color correction would be easy. However, like you, many of my photos don’t and color correction has to be done in post without those aids.
Here are a couple of suggestions that I use on a regular basis. I use the following methods as a first step in almost all my PS edits. These methods are quite good at removing image color casts. I do a lot of photo restorations and one problem is old color prints turning orange with a significant loss of contrast and saturation.
The first method is using the
Auto feature in a curves or levels adjustment layer. After loading the original image into PS, create a curve adjustment layer. Press
opt-Auto to bring up the various auto options. Select
Enhanced per Channel Contrast and
check the Snap to Neutral Colors option. This general does a very good job at removing your color cast. You can try some of the other options to see if any works better, but I found that this option usually works the best.
If the first method doesn’t work as well as I would like, I use a second method. After loading the original image, make a second copy by pressing
alt-j. On the copy, select
Filter | Blur | Average Blur from the top menu bar, Create a curves adjustment layer, select the middle eyedropper and click on the blurred image. You will see the solid color image change to a neutral gray. Turn off the blurred layer. The color cast is generally removed at this point.
There is another simple method using
Neutralize in the
Image | Adjustments | Match Color panel. But I’ve found that this doesn’t work as well as the methods I described above.
After removing the color cast, then you can continue making the other needed edits to your image.
These methods, generally, work well as long as there isn’t a strong background color, such as a small yellow flower in a green forest. If they don’t do the job, then color correcting becomes more difficult.
Below are a couple of examples, one being your image. Without being there and seeing this young man, I can only correct the color to what seems correct to me. As the photographer, only you would know the true colors. And even then, your eye’s may have already adjusted to the ambient colors in the gym.
The first example is from Ctein’s book on Digital Restoration. The left image is the original degraded image I copied from his book, the middle image I applied the first method described above and the right image I applied the second method described above. No other adjustments were made.
For your image, the first method didn’t work very well. However, the second method did a much better job at removing the yellowish cast.
Hope this helps

After the Average Blur, you can see the overall color cast of the image (L). Using the middle eye dropper creates a curves adjustment that brings the average color cast to middle gray (R).
