Of all the macronutrients, protein is most important for cutting. While it will be carbs you miss the most, when cutting down calories, protein is important to build muscle which boosts your metabolism. Therefore, you’ll need to keep up your protein intake. Products such as Whey Protein Concentrate (WPC) allows you to consume a greater intake of protein without overdoing the calories, they are also available in tasty flavours than can curb any sweet cravings too.
Now that you've got the training part down, it's time to stretch it out. (Can you say ahhh?) Stretching while your muscles are warm can help improve your flexibility, says Davis, not to mention it just feels phenomenal after you've pushed yourself hard. A light cool-down is also great for calming the nervous system. While dynamic stretches should be your go-to during a warm-up, the cool-down is where static stretching comes in—this means holding a stretch for 20-30 seconds. These four passive stretches will do nicely.
Start with moderately heavy weights. Picking the right amount of weight to lift is important to build the right kind of muscle and avoid injuries. First, you need to determine your max-out weight: the heaviest weight that you can lift, at least once. Use a spotter and find out your max. Ideally, beginner bodybuilders should be lifting 70-80 % of that single rep max for 6-10 repetitions of 3-4 sets. This is the optimal set and repetition range for muscle growth.
Further suggesting that training to failure plays a lesser role in the hypertrophic response is a study that noted that training to failure with light weight did not produce marked strength gains (meaning that failure itself wasn't the most critical factor).[6] In fact, increasing the resistance of the movement recruits more motor units and is correlated with gains in strength and hypertrophy.[6,7]
After session 12, consider whether you need to increase the weight for any particular exercise. If you can comfortably do more than the RM of 12 exercises, increase the weight by a modest amount, say two pounds or a kilogram for isolation exercise muscles such as triceps and biceps, and 5 pounds or 2.5.kilograms for compound and large muscle group exercises like squats and deadlifts. When using dumbbells, this would apply to each one. Don’t increase the number of sets beyond 3 at this time.
