Never worked out

Nicole
For someone who has never worked out I want to start. I'm 106 pounds, and can't keep weight on me very good. I want to try to build muscle, and tone my body. I'm ttc now over 2 1/2 years, and on my 2 round of clomid. What type of workouts would be safe, and good for a beginner. Preferably right now just home workouts.
