I generally start my adult male students out on 25# bows. It's a good weight for teaching archery form. Most adult male target shooters end up shooting 35-45# bows. Those who are interested in hunting probably end up a little higher in weight, maybe 45-50#. Many hunters, men or women, who don't feel comfortable pulling 45-50# are successful in the 40-45# range, although that is not optimal in my opinion. If a person is healthy, has no physical disabilities, and practices 3-4 times a week, he or she should be pulling their target weight bow comfortably in four to six months and their hunting weight bow within a year.
There isn't as much difference between a 40# target bow and a 50# hunting bow as you would think. Different demands shrink the weight difference. A dedicated target shooter might need to shoot 100 shots a day without pooping out. A dedicated hunter might shoot 10 shots a day, all but 1-2 of which will be practice shots. A dedicated target shooter will probably get in the habit of holding at full draw for at least 2 seconds, whereas a dedicated hunter would be more likely to start his aim as he is drawing the bow, and release the shot almost as soon as he reaches anchor. Multiply that 2 second hold by 100 shots and that equals a lot of energy holding at full draw.
Entry level bows are not known for having high quality strings. However, that doesn't matter as much as the arrows you choose.
I generally start out my 25# shooters with 1.000 spine, 28”, PSE Razorback arrows, which can be purchased already made at Lancaster and probably other places. They are inexpensive, and zip right along out of a 25# bow.
