The English in the passage is poorly-phrased in my opinion.

1. Handling heavier objects may provide opportunites to increae workload intensity in a benign manner allowing for subsequent improvemnts in chidren's physical fitness.
a. what does it meay by increase workload intensity?
b. What is the meaning of in a benign manner?

Let me try to re-phrase the sentence:

"Children's physical fitness may be improved by allowing them to handle heavier objects. By doing so, they can gradually increase their work levels without feeling discomfort."

Does this make it any clearer to you?

2. Dr. John said they(heavier toys) would initiallly most likely serve a niche market for physical therapists to help their young patient.
a.what does it meay by serve a niche marker for physical therapists?
b. also, Does to help mean in order to help ( in other words purpose?) or Does to help modify market?
I would appreciate any answes you provide for me.

The heavier toys have a 'specialist' function; they would probably only be used by physical therapists who help young children with muscular difficulties, rather then by the general public. A 'niche market' is a market that is small, but well-defined.
