If you think of big metal dumbells when we say weights then think again. Bijoux plastic weights are available from half-a-kilo up in a range of bright colours, so you can do low-weight, high-repetition exercises in the comfort of your own home. You can even work out your arms as you sit on the sofa watching Eastenders if you want.
Another good tip are hand and ankle weights that fasten with velcro so you can make your aerobic dancing that bit more energetic. They might feel light when you start off, but after fifteen minutes of pushing tin you'll know they're there.
The most simple things can sometimes be the best. Not only is skipping fantastic exercise, but it's a really good one for involving older children too. Teach them to skip, teach them all the old skipping songs you remember from your childhood and who's exercising?
