No its perfectly okay, there is hardly anyone I see who doesn't have some sort of physical issue to deal with before we put a plan together. You're actually in the majority. And also I understand how you mean about Personal Trainers. The standards out there are quite shocking to be honest. But we're not all bad
I advise against both those leg press exercises you've linked. The reason being, they force the legs to move irrespective of your core, which leads to low back weakness and eventually pain.
If you can, try standing shoulder presses with moderate-light dumbbells. Make sure the weight isn't too heavy, but if you can lift it more than 15 times its too light. This exercise gets your whole body working for a multiplied calorie burn.
Other than that, definately stick with the rower and bike, and start moving toward interval training.
This involves upping the pace slightly for 30 seconds, then bringing it back to a normal, leisurely pace for a minute to gain your energy back. Repeat this method for 15-20 minutes to get a better fat burning workout.
