Home gyms are good for just that..at home. Personally I have a bowflex at home for the days I cant make it to the gym; and working 12 hour shifts there are those days. What I like about the bowflex..gives a decent workout for whatever muscle group. (its important to say a decent..maybe not the best or as good as free weight but decent), it is also compact, not noisy, and doesn't have loose weights everywhere (which is important to me as I have children who seemed to love playing with my free weights when I had them. What I didn't like about bowflex...Price.
As Far as easier or harder than free weights or which has a more challenging workout.....Its all about intensity baby...whether lifting iron or a bag of potatoes.
my 2 sense.
peace.
