You can eat more of these foods for three meals; You can take the method of eating less and eating more meals, and you can't eat too much per meal. The interval between exercise and diet should be 30 minutes to 1 hour, and the absorption after 30 minutes of exercise is better than usual.

In bodybuilding theory, RM is used to indicate the maximum number of repetitions that a load can do continuously. For example, an exerciser can only lift a heavy object five times in a row, so the heavy object is 5RM. Novices can do 8 to 12RM load, and each group can probably do 8 to 12 load. Each group should rest for no more than one minute, and each movement should rest for no more than two minutes. Warm up for 10 minutes before doing the following exercises, and then you can run. Chest: barbell bench press, upward inclined bench press, downward inclined bench press, dumbbell flying bird (4 groups in each group); Biceps brachii: dumbbell bending with one arm and barbell bending (6 groups in each group); Legs: Squat, arrow squat and heel lift (4 groups each); Triceps brachii: dumbbell flexion and extension, narrow push-ups, dumbbell neck and back arm flexion and extension (4 groups in each group); Back: Pull-ups (above 10 as far as possible), barbell bending over, sitting behind the neck (4 groups in each group); Shoulders: push-ups, front horizontal lifts and side horizontal lifts (4 groups in each group); Abdominal muscles: supine leg lifting group 4. Abdominal muscle exhaustion in each group is still 15 to 25. The rest time of each group is 20 seconds to 30 seconds. Abdominal muscles are practiced about three times a week. Exercise chest muscles and biceps brachii for one day, legs and triceps brachii for the second day, back and shoulders for the third day, and rest for the fourth day.
