TRICEP KICKBACKS!! Theyre crazy for tuckshop arms. and the tricep pull down machine thing at the gym is good too - i like to do 20-30 mins weights and 30-60 mins cardio - so for weights i'd do leg press, chest press, bicep curls and hammers, tricep pull downs and tricep kick backs and crunches then i'd vary between the bike, treadmill and cross trainer. That stripped the fat off last time and toned
probably 3-5 times a week.
for your skin drink HEAPS of water - depending on your skin type i am prone to rashes and eczema and i use Avene (when i can afford it) and my skin cleared up well.
