5 foot 10 is roughly 1.78cm.

With a weight of 62kg, your BMI is only 19.6 which is in the low normal range so you don't need to lose weight, just tone.

I like to use my DD for weights, so i do arm presses lifting her up in the air. she thinks it's funny. Walking or jogging can be good for toning too. take bub out for a walk in a carrier or pram.
