The exercise that only wimps leave out of their leg workouts or, an exercise that, although undoubtedly effective, has been a bit overhyped by many trainers. One that may not be absolutely imperative for athletes new to strength training, dealing with past injuries, have structural differences, or even just a lack of available resources at their local gym.
After battling the lasting effects of an old high school hip injury, I eventually quit trying to force myself to barbell squat and began programming alternative movements. These helped me to not only have more comfortable, effective workouts, but are something others can benefit from, either for the reasons above or simply to switch up their usual routine for a different type of stimulus.
Below is a twice-per-week leg training program that leaves out barbell squats altogether, but provides plenty of stimulus to all the major muscle groups of the lower body to continue spurring new growth.
Why These Leg Workouts?
Muscle Protein SynthesisThere are specific reasons behind training legs twice per week. The first reason is for the optimal promotion of muscle protein synthesis (MPS). Research continues to show that protein synthesis within a recently trained muscle group remains elevated approximately 36-48 hours post-workout. 
This means that a trained muscle group is undergoing recovery and experiencing the growth of new tissue for around two days after the workout. Although conventional bodybuilding wisdom says a body part should only be trained once per week, by doing so, after that 48-hour MPS elevation has come and gone, that leaves roughly 4 full days of little to no stimulation in those muscle fibers or subsequent MPS elevation before the muscle group is trained again. This reduces the potential for improvements in muscle growth and strength.
On the other hand, if we aim to train a muscle group twice each week, spaced evenly throughout the week, we will be training a given muscle group just after that 48-hour window closes. Again, promoting further MPS elevations once recovery and growth from the previous session has ended. In the long run, this means optimal muscle stimulus and not leaving any muscle growth "on the table" by waiting too long between training sessions.
Varying Repetition RangesThe second reason why training a body part at least twice per week is a good idea for athletes is the ability to train in a variety of rep ranges. Once again, looking to modern strength-training research, it seems that using multiple rep ranges likely leads to better overall size and strength gains than training in just one rep range throughout a training program. 
This being considered, having two training sessions for a body part each week allows athletes to have a low-rep focused and a high-rep focused workout each week.
Of course, as training progresses, the range of "low" and "high" rep workouts should change, and anything from as low as 1-4 reps to as high as 20-30 reps per set can be advantageous for people training to improve appearance. At the end of the day, from training block to training block, specific rep ranges can and should be adjusted.
But keeping one workout to more low repetition sets and the other to higher repetition sets can help to again maximize training results. This allows for effective workouts even if the "must have" exercises aren't currently in your program.
Some of these exercises are similar to barbell squats in terms of the overall movement pattern. However, these tend to place less stress on the hips and lower back compared to loaded barbell squats. This allows for sufficient overload of each muscle group while helping many people have a safer, more comfortable training session.
Movements like the landmine squat and goblet squat have helped big time in reducing the hip pain I felt all too often when barbell squatting since my past injury, and have actually been part of some of the best leg sessions I've had!
*To further increase muscle repair and growth after workouts, consume a high quality protein source and ample carbohydrates like the combination found in Core PWO!
Why These Exercises?The barbell squat has been an all-time favorite to so many largely due to the amount of muscle fibers activated during the movement. When squatting, everything from the quads to hamstrings, glutes, and even the core and to a smaller degree, calves are activated. A loaded barbell provides for a large amount of progressive overload to be introduced, allowing athletes to easily add weight as they become stronger, and to continue gaining strength over time.
This being the case, too many people fall into the thinking that the barbell squat is the only leg movement that provides this array of benefits. Although the challenge of maintaining stability is lessened, and the movement pattern is slightly altered, it can be argued that squatting movements like the Hammer Strength machine squat, or dumbbell goblet squats could produce very similar activation while simultaneously reducing the amount of load placed on the lower back, and for many. This provides a movement pattern much more conducive to their injury history, and hip and limbs structure.
At the end of the day, two important factors are performing a variety of multi-joint movements that stimulant a large proportion of muscle fibers and allowing for continued progression in training load. Even if your training routine doesn't include exercises deemed "normal" by most gym goers, I would dare say that as long as the necessary intensity is present and programming is correct, there are few exercise that a lifter has to perform throughout their career in order to make significant progress.
Choose exercises that you can safely and correctly perform, continually challenge yourself by lifting a given weight for more reps, more sets, or using more weight, and you can without a doubt continue getting bigger and stronger even with somewhat unconventional resistance training exercises.

|Seated Calf Raise - 90 seconds rest between sets||5||20-25|
So, What Now?Now that you have your leg training planned, a good rule of thumb is to follow a given program for roughly 6-8 weeks before considering changing anything. This length of time allows for the athlete to develop a feel for some movements they may not be as familiar with, improve motor patterns, and of course get progressively stronger in each lift.
If you're still making progress and feeling good with the workout after that time period, then there's no need to fix something that isn't broken! However, as plateaus in a given exercise begin to creep up, or you simply want to change up the exercise selection a bit to keep things interesting and shift the emphasis of each muscle group, below are some other non-barbell squat leg exercises that can be done in addition to varying the amount of sets/rep ranges you train in.
- Walking Dumbbell Lunges
- Dumbbell or Cable Box Step-Ups
- Barbell Hip Thrusts
- Bulgarian Split Squats
- Hack Squat
- Dumbbell Sissy Squats
- Machine Donkey Kicks
Drop It Like a Squat?There's no question that barbell squats are a highly effective leg exercise. For the vast majority of healthy people, I believe they should be a focus of most leg programs.
However, for those just getting into strength training and may not have adequate motor skills or flexibility for a full barbell squat just yet - or others that have old injuries that make them painful to perform - it would be crazy for a trainer not to realize that other options are available, and likely just as effective as long as other variables like training volume, progressive overload, and adequate intensity are monitored correctly. You may not get strong, great-looking legs without doing squat, but you can certainly get them without doing barbell squats!
