Is it possible to perform strength training on certain muscle groups and training for mass gain on others?
For example, I don't want big legs, but I of course want much stronger legs. Can I do strength training on my legs day (low repetitions and heavy weight) while purely working to put size on my upper body on their days (high reps, lower weight)?
OR will my body only do one thing at a time over a given timeframe? By that I mean, if I do my legs day for maximum strength gains and then for the rest of the week do training for size, will my body decide that it should just pack on size everywhere that I trained that week, or still honour my strength workout for legs?
This could include body parts that are related / close together like say if I wanted to have stronger biceps but bigger triceps.
