For strength and conditioning, lifting weights goes hand in hand with jogging. Weights build up the muscles and make the athlete stronger.

that is a gross simplification. The muscle:hypertrophy link is NOT as simple as lifting = size.

err, it sounds a good idea, bulid the muscles of the leg and arm in the same time, in my area, i see a muscle man jogging in a heavy clothes which seem like a bulletproof:) i believe it is more than 15kg, i think it wil build up all your muscles

Rob, could you please type a little more clearly, I'm not sure I understand the point you're trying to make. If what is 15kg/30lbs it will build your muscles? That's not how it works.

Also, running doesn't build up the muscles in your legs, it breaks them down. That is very important to note. Go take a look at some marathon winners, then come back and tell me how big running made their legs.

By forcing your body to work harder, you add more stress to the targeted and supporting muscles.

Remember to use proper form when lifting weight, especially heavy weight. Lifting heavy weight for the sake of lifting heavy will result in poor form which will lead to injuries. You don?t want injuries.

I also thought running would build up your legs muscles, but the example you have given clearly demonstrates that the opposite is true. Would this be the same for cycling then? What can be done to build the leg muscles?

we've all heard the age-old story of weight lifting ...

high amount of weight with small reps = bulky muscle

high amount of reps with small amount of weight = lean muscle

now think about what cycling and running equate to ... tons and tons of reps ... the same with swimming ...

ofcourse getting stronger is good but weight lifting never came in my mind.

I`ve been lifting for some time.I`ve a plan for 3 days in a week.First i work for the bench then go for running finally some aerobics to stretch my body.Weightlifting is good and fun.
