Increased muscle mass does not always equal greater strength. I am of the opinion that it is far more beneficial to be "strong for your size", e.g. being able to perform a high number of body-weight exercises, rather than be a "Manimal" who can outbench 99% of the hardcore lifters in the gym.

Moving a lot of dead weight is impressive, and takes a lot of work. But at the end of the day, it is a one-trick pony. Being able to put your body through long, difficult, fast-paced calisthenic workouts is far more beneficial (and valuable) in today's world.

That being said ( ) I lift weights one week, then the next week I only do calisthenics for upper-body work. I cycle 140+ miles per week (used to run 50+), and I haven't lost anything but some fat. I look more "cut" than I did before beginning cycling, but I haven't lost any muscle mass. I am perfectly happy with that.

In the end, your body will dictate how you will be able to maintain your fitness goal...
