Stretching after each lifting session is extremely important in preventing injury. Flexibility allows your body to become much more able to handle the odd assortment of stresses that are placed upon it each day. I'm sure that the more hardcore of us bodybuilding fans heard that Branch Warren recently slipped and fell, landing on his outstretched hand and tearing his triceps in the process.
Perform three weight-training sessions per week, hitting your whole body each time. Base your routine on compound exercises such as squats, lunges and deadlifts. These burn the most calories, hit more muscles and give the best bang for your buck, claims Rachel Cosgrove, strength coach and co-founder of Results Fitness in California. If you're not sure of any exercise techniques, ask a trainer at your gym for assistance.
Keep your arms almost straight and elbows not quite locked. Raise the handles straight out to the sides and upward to only a couple of degrees above shoulder level without rotating your hands (do not pronate or supinate). Palms should face downward throughout the move. Leading with your elbows, lift only with your deltoid muscles, not with your traps or upper back. Resist during the descent to the starting position. Make sure that the movement is controlled and consistent from the beginning to the end of the set.
Exercises in which you pull the weight perpendicularly into your body—often called rows—were a big part of Arnold's back workout. He favored all kinds of variations—seated cables rows, T-bar rows, bent-over barbell rows—but each one was done with high volume and progressively heavier weights. Arnold followed a pyramid scheme in which he increased the weight on successive sets for fewer reps. Only the heaviest sets were taken to muscle failure.
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.
