Hey, I'm 18 years old and looking at building my body up. I have been going regularly to the gym twice a week for 4 months now and being doing odd exercises at home but nothing too organized. Unfortunately I do not have any exercise equipment at home apart from a rowing machine and 5kg weights. Can anyone recommend a structured home fitness regime that i can follow in between gym times. I usually attend the gym on Wednesdays and Saturdays so can anyone recommend best days in between to exercise and what are the best exercises to perform (concentrating on upper body) with the 5kg weights I have. If you have a regime that works for you please can you share, I would really appreciate it! Thanks for any help in advance, Andy
