You can absolutely keep working out with a sprained ankle, but the type of exercise you do needs to shift based on how severe the sprain is. The key principle is simple: avoid movements that cause pain above a 5 out of 10, protect the healing ligament from re-injury, and use the downtime to strengthen everything else. Most people can start some form of modified training within days of a mild sprain.
Know Your Sprain Grade First
How you train depends entirely on the severity of the injury. A Grade 1 sprain means the ligament is stretched or slightly torn. You’ll have mild swelling and stiffness, the ankle feels stable, and you can usually walk with minimal pain. A Grade 2 sprain involves a partial tear with moderate swelling, bruising, and painful walking. A Grade 3 sprain is a complete ligament tear with severe swelling, bruising, and an unstable ankle that gives out under weight.
Grade 1 sprains give you the most flexibility to keep training with modifications. Grade 2 sprains require more caution and a longer ramp-up period before returning to lower body work. Grade 3 sprains need medical evaluation before you do anything, because a complete tear sometimes requires immobilization or even surgery. If you’re unsure which grade you’re dealing with, the inability to bear weight at all is the clearest sign you need professional assessment before training.
Upper Body Workouts That Avoid the Ankle
The easiest way to stay active is to focus on seated or lying exercises that put zero pressure on your foot. A bench becomes your best friend. Bench press, incline bench press, bicep curls, tricep extensions, and lateral shoulder raises can all be done without your ankle bearing any load. Seated overhead presses, chest flyes, and any cable machine exercise performed from a seated position work too.
You can also do pulling movements like seated cable rows and lat pulldowns. If your gym has a chest-supported row bench, that’s ideal since you’re lying face down with your feet off the ground entirely. For core work, stick to exercises where your feet aren’t anchored or pushing off the floor: think dead bugs, hollow body holds, or crunches on a bench. Avoid sit-up variations where your feet hook under a pad, since bracing through the ankle is unavoidable in that position.
The general rule from Cleveland Clinic’s guidance is straightforward: if you can do it lying or sitting on a bench, it probably won’t pressure your foot.
Using a Pain Scale to Guide Intensity
Physical therapists use a 0-to-10 pain rating to determine whether an exercise is safe to continue. On this scale, 0 to 3 represents minimal pain, 4 to 5 is acceptable, and anything from 6 to 10 is excessive. Your goal is to keep all exercises within the 0 to 5 range.
If pain creeps above 5 during any movement, you have three options: reduce the number of reps, slow down the speed of the movement, or increase your rest time between sets. This applies to everything from upper body lifts (where you might unconsciously brace through your feet) to the ankle rehab exercises described below. Pain is useful information here, not something to push through.
When to Start Ankle Rehab Exercises
For Grade 1 sprains, gentle range-of-motion work can often begin within a few days once acute swelling starts to subside. For Grade 2 sprains, you’ll typically wait longer, sometimes a week or more. These early rehab exercises aren’t just about recovery. They’re part of your workout now, replacing the lower body training you can’t do.
The American Academy of Orthopaedic Surgeons recommends several progressions:
- Alphabet traces: Sit so your feet don’t touch the floor and use your big toe to write each letter of the alphabet in the air. Keep the movements small, using only the foot and ankle. Do 2 sets daily.
- Towel stretches: Sit with your leg straight in front of you, loop a towel around the ball of your foot, and pull gently toward you. Do 2 sets of 10, holding each stretch, six to seven days per week.
- Marble pickups: Place 20 marbles on the floor and use your toes to pick them up one at a time into a bowl. This rebuilds the fine motor control in your foot. Do all 20 daily.
- Heel cord stretches: Stand facing a wall with your injured leg straight behind you, heel flat on the floor. Press your hips forward and hold for 30 seconds. Do 2 sets of 10, six to seven days per week. This one requires partial weight bearing, so it comes later in the progression.
Start with the non-weight-bearing exercises (alphabet traces, towel stretches, marble pickups) and progress to standing movements only when those feel comfortable within the 0 to 5 pain range.
Progressing Back to Lower Body Training
Once you can walk without pain and your ankle feels stable, you can begin reintroducing lower body exercises in a controlled way. Start with bilateral movements where both legs share the load: leg press machines, bodyweight squats to a box, and wall sits. These are more forgiving than single-leg work because your healthy ankle compensates for any instability.
From there, progress to single-leg balance work. Stand on your injured foot for 30-second holds, first with eyes open, then with eyes closed. This rebuilds proprioception, your ankle’s ability to sense its own position and react to shifts in balance. Proprioception is often the last thing to recover after a sprain, and skipping this step is one of the main reasons people re-sprain the same ankle.
Only after you can balance confidently on one leg should you add dynamic movements like lunges, step-ups, and eventually lateral movements or jumping. The progression matters more than the timeline. Rushing to plyometrics or agility drills before your balance and strength are restored is the highest-risk mistake you can make.
Braces and Tape During Workouts
Both ankle braces and athletic tape reduce your risk of re-injury during exercise, and both are better than no support at all. Research comparing the two shows braces are slightly more effective than tape, partly because tape loosens during a workout while a brace maintains consistent support.
Both work through a similar mechanism: the pressure and traction on the skin around your ankle improves proprioception, helping your body detect when the ankle starts to roll before it goes too far. A common concern is that wearing a brace long-term will weaken the muscles around your ankle, but studies have found that the peroneal muscles (the key stabilizers on the outside of your ankle) maintain their ability to fire normally even with prolonged brace use.
A lace-up brace is the most practical option for gym workouts. It fits inside most athletic shoes, provides adjustable compression, and doesn’t require the skill or help needed to apply athletic tape properly. Use it during all weight-bearing exercise until you’ve fully regained balance and confidence in the joint.
Testing Readiness for Full Activity
Before returning to sports or high-intensity training that involves cutting, jumping, or sprinting, you should be able to pass a few functional benchmarks. These include single-leg balance with eyes closed for at least 30 seconds, single-leg hopping without pain or instability, and the ability to complete lateral agility movements at full speed. An international consensus published in the British Journal of Sports Medicine recommends evaluating dynamic balance, hopping and jumping performance, and the ability to complete a full training session before clearing a return to sport.
If you can hop repeatedly on the injured ankle, change direction quickly, and complete a full practice or workout without pain or swelling afterward, you’re likely ready to resume normal training. If swelling returns the day after a harder session, that’s a sign you’ve pushed too far too fast. Scale back and give it more time.
