Bilateral movements, working both sides of your body at the same time, are what most lifters prioritize. However, to optimize your training and get even better muscle-building results, don't leave unilateral movements behind!

Unilateral training involves exercises that use one of your body, as opposed to both. Not many see the benefits in doing this which makes these exercises often overlooked – don't make this mistake! Unilateral exercises can help fix muscle imbalances, improve your balance and core strength, and build functional strength. These are all benefits that will help improve your training performance, including helping you lift heavier and safer!

You don't have to give up your bilateral training for unilateral training, you can easily incorporate both! To make sure you're doing that in the best way possible, keep on reading for tips on how to incorporate unilateral movements into your routine, plus a list of which unilateral exercises to start doing.

How to incorporate unilateral exercises into your routine

Throwing in a few upper body and lower body unilateral exercises into your workout without much thought isn't the best way to reap all the wonderful benefits of unilateral training. Remember, random training, whether it’s bilateral or unilateral, won't give you the best results!

To help ensure that you're incorporating unilateral exercises into your training as effectively as possible then consider following the following tips:

  • Start your sets with the weaker side: One of the main reasons for unilateral training is to fix muscle imbalances. So, you want your weaker side to catch up to the stronger one. To ensure that you're bringing the weaker side up to meet the stronger side, work that side to fatigue first! Then do the same number of reps on the stronger side. This will allow you to strengthen both sides equally that way the weaker side is no longer playing catch up.
  • Considering doing unilateral exercises before bilateral ones: Everyone says to start with your heavy sets first, which are usually bilateral compound lifts. This is good advice, but there's nothing wrong with doing it the other way around. If you really want to focus more on fixing muscle imbalances, then consider starting with unilateral exercises! It will help to activate the muscles that are normally not working to their full potential during heavy bilateral lifts. You may run the risk of fatiguing your muscles before your big lift, but there's a high chance that you'll be able to lift more because the muscles are firing better in unison.
  • Pause before switching sets: Train each side as an individual set by pausing for a short rest period in between each group of reps. It might be easier with a lighter weight, but if you're lifting a challenging weight then take a little break before switching to the other side. Doing this will help ensure that your form doesn't break down before the end of your set. Take a 15-second rest period between sides, but if you're going heavy and feel fatigued then rest for a period of up to a minute.
  • Don't start heavy: Since you're only using one side of the body, you probably won't be able to lift as heavy as you normally would. This means you should avoid starting heavy! You may be able to squat 100+, but lunges and split squats may be a different story... So, start light. Going too heavy too soon will make it harder for you to balance which can result in an injury.

Best unilateral exercises

Lunges aren't the only unilateral exercises in the world. They're great and definitely should be incorporated into your routine, but one leg may dominate a little more than the other, but it doesn't place full focus on one particular side.

Keep lunges in your routine, but include these unilateral exercises in your training as well...
