yea you can try interval training like what lianamaster
suggested..
you can try the method they do in BMTC, called speed training,
where u try to sprint at a 80% pace for 60 secs, and then jog for
90 secs, den start sprinting for 60 secs again..
for a start maybe u can try doing 8 sets of sprints, and over
time u can increase ur sets and also ur sprinting pace..
time to time u can also do a distance run of 3 to 4km..
i did the above training for a month, and my 2.4km timing went
down almost 2 minutes.
of course, you've gotta stay focused and committed..
yea... quite effective on me... can lose weight also...
