So, for example, with the moves above you'd do 15 squats followed by 15 push-ups. Take a little breather then repeat that two more times. Then you move on to your walking lunges and lat pull-downs (and repeat those three times total, too). You can really do anywhere from eight reps to 15 (and even just two sets, if you don't have time for three), but "it’s not a bad idea for beginners to start with a 15-rep range to get comfortable with the exercises," says Davis. And while there's some debate over whether three sets of an exercise is really best, "it’s a great beginner model," says Davis. Don't overcomplicate things when you're just getting started.
That’s it for Basic Strength and Muscle. Novices and casual exercisers can expect a 20-40 percent increase in strength and some muscle size and muscle endurance enhancement. You could continue with this program beyond the 18 weeks by increasing the weight load as strength and capability improves. However, further progress may depend on alterations in exercise variety, frequency and timing. The next phase should be an intermediate program designed to enhance the progress you’ve already made.
Usually, people associate the word diet with days of starvation and pain. However, that is not the correct definition of a diet. The word diet refers to the food choices that we make on a daily basis. Even if you don’t think you that you are on a diet, guess what?! You already are following a diet. Whether you eat candy all day every day or oatmeal, that is your diet.
"Start with two days for two to three weeks, then add a third day," says Davis*.*"Ideally, you should strength train three to five days per week, but work your way up—starting off at five days a week might shock your body." Here's a comprehensive three-day-per-week plan to get you started. Aim to complete 20-minute sessions, then gradually add on time in ten-minute increments until you're working for 45 to 60 minutes, suggests Davis.
Overtraining occurs when a bodybuilder has trained to the point where his workload exceeds his recovery capacity. There are many reasons why overtraining occurs, including lack of adequate nutrition, lack of recovery time between workouts, insufficient sleep, and training at a high intensity for too long (a lack of splitting apart workouts). Training at a high intensity too frequently also stimulates the central nervous system (CNS) and can result in a hyperadrenergic state that interferes with sleep patterns.[51] To avoid overtraining, intense frequent training must be met with at least an equal amount of purposeful recovery. Timely provision of carbohydrates, proteins, and various micronutrients such as vitamins, minerals, phytochemicals, even nutritional supplements are acutely critical. A mental disorder informally called “bigorexia” (by analogy with anorexia) may be held accountable of some people overtraining. Sufferers feel as if they are never big enough or muscular enough, which forces them to overtrain in order to try and reach their goal physique.[52]

2) Make your own home gym. In talking to thousands of trainees, it seems like the majority is better served by attending a health club as most people do not have the motivation to workout at home. However, if you are like me and like to workout in total solitude, this may be the best option for you. The advantages are obvious: no fees, no crowds, you can superset alot (move from one exercise to the next with no rest), and workout anytime. Disadvantages are that you have no one to spot you so you need to be very careful with what you are doing.

Start standing with feet shoulder-width apart and dumbbells in hand. Hinge at the hips so that back is nearly parallel to floor and micro-bend knees. Let the dumbbells hang straight down, palms facing each other. Keeping back flat and torso still, engage back muscles to lift arms straight out to sides until they’re in line with shoulders. Your upper body will form a “T.” Return to starting position then repeat for 3 sets of 12 reps.
Overload Management. The basis of strength and conditioning is progressive overload. It takes some skill to judge the point at which overload—increasingly heavier weight—is building capacity yet not making you too sore, ill or fatigued to continue. That’s why it’s very important to start slowly and build. When in doubt, take a rest, miss a session but don’t alter the program detail, the reps, and sets, if you can help it. The squat and deadlift can be very taxing, so be careful not to lift too heavy for a start.
For every person who lifts weights these days, it seems there are two who have a podcast about it. There are more bodybuilding tips promising greater strength and muscle than ever before, and along with them a ton of confusion; one buffed-up Instagrammer says lifting heavy will get you swole, while a well-known fitness personality has claimed in recent years that two 30-minute workouts per week netted him 34 pounds of muscle in a month.
