...else knows without a stopwatch? i want to lose 15-20 lbs in about 3-4 weeks but im going away to camp this week and you are not allowed to have phones & i dont have a stopwatch or timer if you know where i can get a real cheap one then tell me but id rather not have to buy one for one week

i just need some good workout routines i can try when i first wake up and before i go to sleep because i dont want anyone to know i am doing this
