Actually a women, like any man beginning a serious wokout program, should be concerned with a whole body workout as a beginning phase. Giving it a good 3 to 4 months of a breaking in period. She should avoid attempting any thing near a split during this period. Get the body accustomed to general BB'ing first. Stick to the 3, or even 2 ,day a week training sessions. No SS's, tri sets, etc at this time. The rest period between sets should be between 90 to 120 seconds. This is also not the time to try and push or rush her workouts. This is probably the main reason that so many people quite working out, lifting starts to become work rather than an enjoyable experience. The purpose is to establish the habit of working out as an experience looked forward to, not somethin akin to torture.
Some women will choose a machine over a BB or DB. For some reason, free weights may seem threating at first. Machines may look less intimidating. And than again, some women are the direct oppisite, feeling that machines are those big ugly monsters things. And all those chrome DB/BB are more attractive. They
will learn to love both as time goes by. (I find that the younger a women is, the more it does not matter which form of equipment is used) So it might be suggested to mix up the equipment for a women's training at the beginners stage. Like pec deck/cables with DB benches, leg extensions with squats,etc, etc, etc.
The first 2 weeks, just one exercise per muscle group , 2 sets only. The main concern should be on form/ROM and getting the mental attitude geared towards training as well as the physical. Branch out after the 2 week period with 2 execises per body part. Make one a machine or extension movement if desired. But have the main movement a compound exercise. Reps between the classic BB'ing range of 8 to 12 . Women can develop very good strength, so encourgement to using using moderate weight for BB'ing purposes is suggested. Never stay limited with just using light weight for endless reps and sets. Or even heavy weights for 5 to 7 rep range after a reasonable breaking in period. Make no mistake about it, some women can be very tough when it comes to working out. Good Luck.
