I am 49, female, 5ft 4 and 10st 13 today so BMI about 26.
I’m on a weight loss plan (lost 4 stone so far, since last year), and now need to develop some muscle tone whilst losing the final stone or so in weight.

I do some exercise most days, I have my own horse so ride for 45 minutes to 2 hrs a day, and then all the general walking around, and yard work associated.

I want to do some exercise at home, twice a day as between the riding and a fulltime job I just wont get to a gym!

I have a reebok step, a resistance band, a hand strength gripper, and a set of dumbbells, 1.5kgs, 3kgs, and 5kgs.

So far I’ve worked out to do (twice a day)
Situps (3 sets or 15)
Pressups (from the knees - 3 sets of 15)
Crunches
Side leg lifts
10 minutes stepping, 25 per minute.
Some resistance band work

So how do I start using the dumbbells, a nd what else can I add in?
