I will be 21 years old in january 2014. Height=5.8 foot approx weight= 65kg / 143.3 pound approx.
I do 100 push ups in 4 sets = 25+25+25+25 and 80 leg raises in 4 sets = 20+20+20+20 (I complete it in 40 to 45 mins). I do it 5 days a week, Monday to Friday and take rest on Saturday and Sunday to relax muscles.
Is it ok to build good biceps and 4 or 6 pack abs? I am a computer science student so I have to spend much time sitting in front of computer and don't get much time to walk or play any sports.
I think I walk nearly half a mile or little more than this in my daily routine. I sleep 6 hours or 6 and a half hour every night.
