Q: Don't work out any one muscle group more than twice a week. Your muscles need time to rest and repair in between workout sessions - that's when they build and get stronger. You can work your pecs and abs on the same days, or alternate days. Either way will be just as effective. Set a schedule for yourself so you never skip a workout. Committing to your workout regimen will increase your chances of success. This means doing one type of exercise right after another without a break in between. Supersets make your muscles work harder, and can be an effective way to build muscle fast. For example, immediately follow your bench press with a few sets of pushups. This is called bracing your core. When lifting heavy weights you should always tighten your abdomen to avoid back injury. This has two additional positive effects on your workout. First, you end up strengthening your abs as you work out your pecs. Second, tensing your core will give you a lot more power during your pecs exercises. This will help you see results much faster than if you don't pay attention to your abs during your pecs workouts. You'll end up plateauing if you don't. Once you find you're able to easily bench a certain weight for more than 10 reps, it's time to add more weight. Same goes for all the other weighted exercises - when you can lift more than the recommended amount of reps without feeling the burn, add weight to keep the pressure on your muscles to continue building. Don't be tempted to add more weight than you can handle. You could injure yourself - completely negating all your hard efforts - if you try to lift too much. If a certain amount of weight is too heavy to lift more than 5 times before giving out, you're lifting too much.
A: Work your pecs and abs twice a week. Superset two or more exercises. Tense your abs when you work out your pecs. Add weight as you gain strength.

Q: The most important thing you can do to make sure annoying situations like nagging don't occur is to simply stay in good touch with your parents. Most of the time, nagging happens because of a lack of initial communication. Making sure both sides are voicing their feelings equally will limit the amount of nagging in the future. Especially if most of your relationship with your parents is defined by a lack of communication and tendency to argue, openly communicating can be a very difficult thing to accomplish. Be patient if it doesn't come naturally at first; say what you feel, ask what they're looking for, and let them know they have your ear if something ever bothers them. From there, the pieces will fall into place given time. While parents haven't likely considered how unhealthy constant pestering is for you, it's even less likely they've considered their own health. If nagging is a severe problem in your household, getting together as a team and looking for alternatives to nagging will almost certainly be a relief for both parties. Once you're speaking candidly about how you're feeling, it may be helpful to get together and list down some clear boundaries. While writing down rules to limit nagging and other annoying behaviour might seem overly official, having the rules on paper will give either side something concrete to bring up if a rule is broken. This is about as simple as it gets: if you tell them what they want to know before they ask, they won't have a reason to ask in the first place! If your parents are constantly annoying you looking for information, you can avoid the most stressful part of the formula by letting them know ahead of time.  The strongest example of this would be if you're going out at night. While most parents will want the know where, and with whom you're going, writing the basic details down on a piece of paper and giving it to them will likely set their hearts at rest. To some extent, this advice could also apply to your parents bothering you about chores. Instead of waiting for them to nag you, doing the scheduled task ahead of time will put you at an advantage; you won't be doing any more work than you'd usually be doing, but you'll have proven that you're responsible and proactive, and that nagging you serves no productive purpose. Even if you and your parents come up with some rule against nagging, it's likely they'll end up forgetting once in a while-- after all, your parents are human too! If they ever nag you again after a rule is in place, calmly let them know what they're doing isn't good for either of you.
A:
Maintain open communication with your parents. Explain that nagging is unhealthy for both sides. Establish some boundaries with them. Give your parents information pre-emptively. Remind them if they ever nag again.
