How can I increase/help my immune system? This is the second time I've been sick in 2 months

[kkandbb]

I work out twice a week doing weight training so I guess I'm putting too much strain on my immune system by doing intense (sort of) infrequent exercising but I'm not going to stop my weight training.

How can I increase/help my immune system? I hate down time! But I'm not going to risk my gains and prolong this sickness by working out. And I do try stay away from sick people and I wash my hands a lot but to no avail.

I do exercise. Just not the "good, immune helping" kind.

lots of fruits/veggies and sleep typically does it for me. the exercise shouldn't be a problem since it's only twice a week. it's what you do in between your workouts that counts (ie. diet, stress levels, and sleeping patterns)

Healthy diet, exercise, and echinacea (vitamin that strengthens your immune system)

Vitamin C, helps the immune system quiet a lot. Eat more as well...

Some people are just born with great immune systems and others are not

Sleep, sauna, ginseng and echinacea
