The weighted seated calf raise (version 2) is a calf-strengthening exercise performed by sitting on a bench or box and placing a weight plate or dumbbell across the lower thighs rather than using a dedicated calf-raise machine. Because the knee is bent at roughly 90 degrees, the gastrocnemius is in a shortened position and the soleus — the broad, flat muscle beneath it — takes on the majority of the load. It is an effective option for building lower-leg thickness and endurance wherever machine access is limited.

How to do the Weighted Seated Calf Raise (VERSION 2)

  1. 1Sit on a flat bench or sturdy box with your feet flat on the floor and your knees bent at roughly 90 degrees, hip-width apart.
  2. 2Place a small step, low platform, or weight plate on the floor so the balls of your feet rest on it, giving your heels room to drop below the level of your toes.
  3. 3Set a weight plate on end or lay a dumbbell across your lower thighs, just above the knees. Hold it in place with both hands throughout the set.
  4. 4Sit tall with a neutral spine and brace your core lightly to keep your torso stable — do not hunch forward or lean back.
  5. 5Push through the balls of your feet to raise your heels as high as possible, squeezing the calves at the top of the movement.
  6. 6Pause for one count at the peak contraction, then lower your heels in a controlled manner until they drop just below the level of the platform.
  7. 7Repeat for the target number of reps, keeping the tempo smooth and the weight steady on your thighs throughout.
  8. 8At the end of your set, secure or hand off the weight before standing so it does not slide off your legs.

Form tips

  • Use a raised surface under the balls of your feet — even a 25 lb plate works — to get a full stretch at the bottom of each rep; without elevation the range of motion is cut short by the floor.
  • Pause at full plantarflexion (heel as high as possible) for one count to maximize soleus contraction instead of rushing through reps.
  • Use a 2–3 second lowering phase; a controlled descent increases time under tension and prevents the bounce reflex from stealing the muscular effort.
  • Center the weight over the meatiest part of your lower thigh, not on the knee joint itself — knee contact creates discomfort and can cause the plate to slip.
  • Calf muscles adapt quickly to repetitive loading, so vary rep ranges across sessions: higher reps (15–25) with a pause work well for the soleus, which is predominantly slow-twitch.

Common mistakes

  • Bouncing at the bottom of the rep instead of controlling the descent — elastic rebound from the Achilles tendon replaces muscular effort, which dramatically reduces the effective stimulus on the soleus.
  • Loading more weight than can be held securely, causing the plate or dumbbell to shift and forcing a shortened range of motion just to keep it in place.
  • Skipping the raised surface under the forefoot — without elevation the calves are never fully stretched at the bottom, which limits soleus development and removes half the functional range.
  • Allowing the knee angle to open significantly above 90 degrees as fatigue sets in — a more straightened knee re-engages the gastrocnemius and reduces the soleus isolation that defines the seated variation.
  • Rushing through reps with a fast, uncontrolled tempo — momentum replaces tension and the soleus, a muscle that responds well to sustained time under tension, receives far less of a training stimulus.

Frequently asked questions

What muscles does the weighted seated calf raise version 2 work?

The bent-knee position shortens the gastrocnemius, shifting the majority of the work to the soleus, the deep flat muscle that forms the bulk of the lower calf. The gastrocnemius contributes minimally in this position, making the seated variation the most direct way to target the soleus specifically.

Why do seated calf raises with a weight on my knees instead of a machine?

The machine-free version requires only a bench, a small raised surface, and a weight plate or dumbbell, making it accessible in any gym or home setup. The mechanics and muscle recruitment are essentially identical to the machine version — the bent knee is what determines which part of the calf is trained, not the equipment.

How much weight should I use for the seated calf raise version 2?

Start with a load you can hold securely without it shifting — typically one 25–45 lb plate or a light-to-moderate dumbbell. The seated calf raise is an isolation exercise, so a full range of motion and controlled tempo with moderate weight produces better results than maximum load with a shortened, bouncy rep.

How is the seated calf raise different from a standing calf raise?

In a standing calf raise the knee is straight, which lengthens the gastrocnemius and makes it the primary muscle trained. In the seated version the bent knee puts the gastrocnemius on slack, handing off the work to the soleus. Training both positions is the most complete approach to calf development because they stress different muscles.

How many reps should I do for seated calf raises?

The soleus is predominantly slow-twitch and responds well to higher rep ranges — 15–25 reps per set with a controlled tempo and a brief pause at the top is a common and effective approach. Lower rep ranges with heavier loads can also be used for strength, but the difficulty of holding a plate securely tends to limit how heavy you can go.
