Due to changes in my work situation, my gym membership cost is going to increase significantly. To save the monthly cost, I was considering getting some dumbbells and doing workouts at home three or four times a week.
At the moment, I go the gym three or four times a week, doing mainly cardio (rowing machine and cross trainer) and a bit of free weights (3 sets of 10 reps). This is because I'm not after muscle gain, I'm just trying to keep fit.
Is it sensible/possible to have a keep fit work out with dumbbells? I've seen people claiming that their regime is a full body work out, but is that enough to keep me fit?
