Start by looking at your current home routine and picking one movement pattern, like a row or a squat, where working one arm or one leg at a time would add something useful. Add a single-arm or single-leg version next to your two-sided exercises instead of swapping them all out. Then pick a version you can control on both sides, and build up slowly.
That is the core of unilateral strength training: you train one limb at a time as a planned complement to bilateral work, where both arms or both legs move together. The sections below cover where to add it, which moves to try, and how to tell whether a version suits you.
Add unilateral work without dropping bilateral exercises
The simplest starting point is to add, not replace. For people who already exercise and want a small change, unilateral exercises may be a useful addition to their program. Nothing in that guidance tells you to give up squats, two-arm presses, or other bilateral lifts that still serve your goals.
To decide where the new move goes, scan your current session and name the patterns you already train. Maybe you squat, push, and pull. Choose one of those patterns and give it a one-limb partner. This is a practical way to choose, not a fixed programming rule, but it keeps the new exercise tied to work you already do.
The American Council on Exercise gives one concrete lower-body version of this idea. You can alternate box step-ups with bilateral squats: do a set of step-ups, then a set of squats, then your second set of step-ups. Your squats stay in the plan, and the step-ups add single-leg work around them.
Treat that pairing as one example. It does not set a weekly frequency, a number of sets, or a ratio of one-sided to two-sided work. Start with one added movement, see how it fits your session, and adjust from there.
Choose a single-arm option for an upper-body pattern
Match the single-arm move to an upper-body pattern you already train. Colorado State University lists these single-arm exercise examples:
- Single-arm biceps curls
- Single-arm triceps extensions
- Single-arm lateral raises
- Single-arm shoulder presses
- Single-arm chest presses
- Single-arm bent-over rows
This is a menu, not a ranking. No move on it is required, and the order does not mean one is better or easier than another. If your routine already has a two-arm row, the single-arm bent-over row is the natural partner. If you press overhead with both arms, the single-arm shoulder press fills the same role.
The list also does not tie each move to a specific tool. So pick the option your current home setup already lets you load and control with one hand. If your equipment can't do a certain move with one arm, choose a different item from the list that fits the same pattern instead of improvising a setup.
Choose a single-leg option for a lower-body pattern
Pick the single-leg move that fits the lower-body work already in your plan. Colorado State University gives these single-leg exercise examples:
- Lunges (forward, side, or back)
- Box step-ups
- Single-leg push-offs
- Single-leg squats
As with the upper-body list, treat these as options, not a step-by-step progression. The order does not show which move is easiest or which one to master first.
Equipment guidance exists for one of these moves. The American Council on Exercise guidance recommends bodyweight step-ups for newer exercisers and says handheld dumbbells can be added for intermediate to advanced clients. That advice is specific to the box step-up. It doesn't tell you how to load a lunge or a single-leg squat, and it doesn't cover bands.
If you want more context on squats, lunges, and other lower-body basics, our home lower-body workout guide covers equipment, warm-ups, and mistakes to avoid when you build a full leg session around these moves.
Choose a controllable option and observe both sides
Choose the version you can move with control on each side, and add challenge only as that control holds. You do not need specialized gear to start. As noted in guidance on home-based resistance training, bodyweight and band exercises effectively build strength when progressed gradually over time.
That guidance is general and does not match each one-limb move to a piece of equipment, so the control cues below matter more than the tool you use.
The single-leg squat shows how to use those cues. The National Academy of Sports Medicine suggests you use sturdy support and limit depth to what your mobility and balance allow, and keep control the whole way down. Here is a simple way to apply that:
- Set up support. Stand next to a sturdy surface you can hold. If you're new to the move, NASM suggests holding on with both hands.
- Pick a depth you own. Lower only as far as you can go smoothly. A shallow, steady rep beats a deep, jerky one.
- Finish one side, then switch. NASM describes doing all reps on one leg before switching to the other.
- Compare the two sides informally. Notice whether each side met the same cues: steady balance, the same depth, and a controlled descent.
- Adjust the support, not the goal. If one side wobbles, keep more hand support or a shallower range for now. As balance and strength improve, reduce hand support gradually.
Treat what you notice in step 4 as an observation, not a test score or a diagnosis. One side feeling harder doesn't prove a problem, and it doesn't call for a particular fix. It simply tells you which version to use for now. If a movement causes pain rather than just effort, stop it and review the warning signs in our home workout safety guide before going on.

FAQs
How is unilateral training different from bilateral training?
Unilateral training works one arm or one leg at a time, like a single-arm row or a step-up. Bilateral training uses both limbs together, like a squat or a two-arm press. In a home plan, unilateral strength training usually sits next to bilateral work, so each side has to do its own share of the work.
Do lunges count as a single-leg exercise?
Yes. Colorado State University lists forward, side, and back lunges among its lower-body unilateral examples. Both feet stay on the floor, but one leg does most of the work during each rep. That makes lunges an easy way to add one-sided lower-body work without extra gear.
Can I add unilateral moves if I'm new to strength training?
You can, as long as you choose stable, simple versions. ACSM's general starting advice in its resistance training guidance is to train all major muscle groups at least two days per week and build gradually over time. Unilateral exercises can be added into that routine, provided you progress at your own pace.
What if one side keeps feeling weaker over several weeks?
A steady difference is worth noting, but it isn't a diagnosis on its own. Keep using the version both sides can control and track how each side moves over time. If you want a longer, structured single-side plan, our guide on fixing muscle imbalances at home lays out an eight-week approach. If the difference comes with pain or a recent injury, check with a qualified health professional first.
