Workout ideas for busy mom

Do you have a playground nearby that you could use to do workouts? When mine were that age I use to go to the playground and use them as my weight while I did squats, step-ups, lunges, shoulder presses, etc. If they are a weight you can handle then it works great for a workout-on-the-go. My son would climb onto my back and he thought it was super fun. If you have a baby you can just baby-wear them.

My routine went something like this (my son was 1-2yrs at the time then got too heavy):

Arrive at the playground and walk around in the pebbles for a warm-up either carrying my son or having him balance along on the sides of the playground enclosure. Throughout the workout I would give my older son something to do alongside me if he wanted to be "on me" lol. Usually he lost interest and would just play next to me while I did the exercises.

Circuit:

Walking Lunges with baby - 10 reps each leg
Tricep dips - 8 reps, you can lean up against the side of the playground equipment or use dip bars if they are there.
Chin-ups - 6-8 reps or as many as you can do using monkey bars
Squats - bodyweight or with baby 10-15 (I would go til failure)
Push-ups - 10-12 (child can sit on your back) and you can do them on the equipment for incline push-ups.
Step-ups - 12 ea leg using stairs on playground with or without child in arms

Rest and repeat as many times as you want. When my son got older I would add in a run around the playground in the stroller, but with two this would be difficult.

Of course this circuit would be done as your children permit you without time constraints. Just enjoy yourself!

Hope this helps!
