The second law of motion will impact them because of unbalanced force. As for a fitness activity that a overweight person could do...long as the things they are moving are bigger than them it could have an impact, speed walking.
Newton's second law says that:
The rate of change of momentum of a body over time is directly proportional to the force applied and occurs in the same direction as the applied force.
We can write the law as:
[tex]\frac{dP}{dt} = F[/tex]
Where F is a force, and P is the momentum.
Remember that the momentum is defined as the quantity of motion, such that:
P = M*V
Where M is the mass of the moving object and V is the velocity of the moving object.
Or we can write the second law as:
F = M*a
M = mass
a = acceleration
What this law implies for the fitness routine of someone who is significantly overweight?
Well, for this person the value of M will be larger.
Then if this person and another person with a smaller weight run at the same velocity, we will see that the momentum of the larger person is larger.
Thus, the heavier person needs to do more force to accelerate. And remember that, as more force you do, the more tension you put on your muscles, this is why we can find a link between the second law of motion and the fitness routine.
Also think that only to stand up, you need to do a force that cancels in some way your weight. If your weight is larger, then the force you need to do is larger. This has a really big impact when running or jumping, an overweighted person would need to do a lot of force with his/her legs, and it can cause an injure.
Now for the second question:
Yes, an example of it can be weight lifting. Think that the person can be sitting and only need to use his/her arms to lift a given weight, thus the weight of the person does not have a lot of impact in this exercise.
