A number of studies have shown that heart failure symptoms can be improved with a special type of pacemaker. It paces both the right and left sides of heart. This is referred to as biventricular pacing or cardiac resynchronization therapy. Ask your provider if you are a candidate for this.
Five sets of bench presses are recommended for most people. On heavier days, warm up with a set of 10 repetitions at about 50 percent of body weight. Then do one set of 8 repetitions, one with 6 and one with between 3 and 5 repetitions. Try to get at least 2 to 3 repetitions on the last set. Only power lifters and experienced bodybuilders should max out on the bench press.
So the low down on reps is 4 to 6 for all heavy sets. Warm up sets and intermediate can be 8 to 10 reps, but to get the muscle stimulating benefit of weight training, you must use lower reps to create enough of an overload. The amount of heavy, intense sets per exercise will be between one and three sets, depending on the order of the exercise.
