Get a kettlebell. One piece of equipment that doesn’t take up a lot of space. Get one that is a little bit heavy for you to pick up, not too light. I can’t recommend what weight for you though
Use it for 10 minutes per day, do squats, cleans, snatches, shoulder press, swings and Turkish get ups.
kettlebells are off center weighted so that your whole body is involved when using them, so doing those exercises will work your core, back, legs, upper body, and will also be great cardio for your heart.
one simple suggestion! The problem with biking, exercise like that is you have to do it for a long time! Do it with a weight for 10 minutes straight and be done
im not a mother, nursing student though, but that is one simple suggestion
