Hi Guys, hope this is a right place to ask. I'm approaching 40..and due to busy lifestyle I haven't been exercising the past few years. BMI is normal, just want some advice to get fit. Used to be a school swimmer back in the days... thinking to take up swimming again.. anyone can advice on how to start again? I know breast stroke and free style. Looking for plans to build up strength again. I would say my fitness level now is low.. start to feel aches and pains and weak.
