Supergirll - As an alternative, you can switch to low volume workouts 2-3 times a week, working at high percentages of your single rep maximum (1RM).

This kind of training using compound movements is GREAT for muscle tone/strength and burning lots of calories, but won't elicit a lot of muscle growth. You can perform the exercises one at a time, or in timed intervals for a little extra intensity.

Another alternative would be to simulate some of the kettlebell exercises using dumbbells, barbells and even medicine balls. Two to four, 20-30 minute sessions a week will keep you tone/strong and help to burn lots of extra calories.

If you would like some examples of how to do something like this, I can put something together for you.

Almost everyone will experience a little bit of muscle gain at first. Without plenty of quality protein/fat calories and optimal weight training, muscle gains will level out before to long.
