Any good workout programs for women?

Lifting a bit is a good start. Beginner level programs won't be gender based, so she can benefit from any beginner linear program.

Candito Linear Control and the many posts on Greyskull LP here are good starts. Building muscle will assist in fat burning moreso than adding more cardio. Diet, as always, is big with bodyfat levels.

Kettle Bells at home bro

gives them no excuse and its an amazing workout

The best way for her to get more lean if she is alread tiny is to build muscle. Focus on compound lifts (dB/ B.B. chest presses, leg presses/squats, shoulder presses, etc) with a few supplemental lifts at the end of the workout. Do this type of workout 3 days per week (I.E. Mon, Wed, Fri). The other 3 days (Tues, Thur, Sat) do cardio (30 minutes should suffice). Make sure to warm up well dynamically before the work out and stretch after the workouts. Diet should be 5 to 6 small to medium size meals per day with adequate protein intake. Plenty of fruits and vegetables are important as well.

I’m a garage gym guy but I felt like my wife could benefit from CrossFit. She certainly wasn’t big by any measurement. She is a homeschool mom of 4 and I thought it would be good for her to to get out a few times a week. At first the money concerned me but I have to say I pay it gladly now. She looks amazing after about 9 months. I could not be more impressed with what CrossFit has done for her.
