I used to work out very regularly, since having kids I've always worked out, but don't really have much of a routine or schedule. Now that they're 3 1/2 and 1 1/2 I want to tighten things up, both myself and my work out routine. I'm going to plan a 1/2 marathon for the spring. I can easily do 4 miles now, so it will take some training, but nothing outrageous.
I can get to the gym for about 40 min, and do about 10-15 min of abs and push ups at home. If I aim for 4 gym days, do you think I should focus on running two days and weights 2 days or do shorter runs (20 min) 2 days and 20 min of elliptical the other 2 days with 20 min of weights everyday?
Any other tips for toning and tightening I'd appreciate. I'm in decent shape, but I really want to get bikini ready.
