Hey everyone. This new year I have a goal of putting on more muscle. I’m a pretty fit 15 year old, considering I lost 20 lbs. last autumn. I exercise at home because I have dumbbells and a bench press. So here are a few questions about arm exercises:

1) Would you recommend working out 20 minutes a day or 45 minutes every other day?

2) What should my diet look like? Should I increase caloric intake, eat more protein and less of something else?

3) What arm exercises have you noticed results with?

Thanks everyone! Have a happy new year.
