Exercising 4 times a week is a little impractical at the moment, what with job hunting & internship etc. Three times per week is the minimum recommended amount, AFAIK, and seems much more achievable.

Unfortunately, my gym membership is suspended until the beginning of September due to lack of funds. However, there are other forms of exercise that I can do until then – running, sit-ups & squats etc at home, rollerblading. The weather is no longer quite so hot, and my knee is much better now, so no more excuses!
