Instead of going to town on the abductor and adductor machines, try compound exercises like side lunges and curtsy lunges that target the adductors and abductors while also hitting the larger muscle groups of your lower body -- your glutes, quads, hamstrings, and calves.
Weighted glute kickbacks
Look, I get wanting to have the booty of a Kardashian, but spending hours on the weighted glute kickback machine isn't the solution, especially when you're crunched for time. Squats and deadlifts each require significant engagement of the glutes, and they’ll also target the other muscles of your lower body, as well as your core. Sub them in for the kickback machine and perform at least two sets to exhaustion.
Standing calf machine
There's nothing wrong with working your calves, but the standing calf machine isn't your best bet. Because you support the machine's weight across your shoulders, you end up carrying much of the added resistance with your back, rather than loading it directly on your calves. You can more effectively isolate your calves with single-leg standing calf raises, or you can target them during functional movements, such as sprinting, plyometric box jumps, or high skipping.
