Calf Raise Machines

Calf raise machines are easy to overlook. But full calf development needs both a straight-knee and a bent-knee loading angle. Standing and seated formats each provide one, and actual training research backs that up, not just anatomy textbooks. Our lineup covers standing, seated, and combo leg press/calf raise machines. We carry Premier Strength, Cybex, and Star Trac, new and refurbished.

Types of Calf Raise Machines

1

Standing Calf Raise

Full range of motion with the knee extended. The classic gastrocnemius-emphasis format.

2

Seated Calf Raise

A knee-flexed position that shifts emphasis to the soleus, underneath the gastrocnemius.

3

Leg Press / Calf Raise Combo

A calf block built into a leg press carriage. One station covers both movements.

Standing vs. Seated: What the Research Shows

A 2023 controlled training study (Kinoshita et al., Frontiers in Physiology) tested this directly instead of relying on a single-session EMG reading. Fourteen untrained adults trained one leg with standing calf raises and the other leg with seated calf raises, 2 sessions a week for 12 weeks, then had both legs scanned by MRI to measure actual muscle growth.

  • Gastrocnemius: grew far more from standing training. Lateral gastrocnemius volume increased 12.4% on the standing leg versus 1.7% on the seated leg over the 12 weeks; medial gastrocnemius increased 9.2% versus 0.6%.
  • Soleus: grew about the same either way, 2.1% standing versus 2.9% seated, no meaningful difference between positions.

In practice: a standing unit drives more total calf growth if a floor can only add one machine. Programming both angles is what trains the full triceps surae (gastrocnemius and soleus together), which is why we carry both formats. Read the full study.

Which Type Fits Your Floor?

Type. Best For. Footprint. Resistance. Example in Our Lineup. Starting Price.
Standing. Full range of motion, gastrocnemius emphasis. Standard footprint. Plate-loaded. Premier Strength Beast Series Calf Raise. $1,599.
Seated. Soleus emphasis, knee-flexed position. Standard footprint. Selectorized (weight stack). Cybex Seated Calf Raise. $995.
Combo (Leg Press/Calf Raise). Space-limited floors needing both stations. Shares leg press footprint. Selectorized (weight stack). Star Trac Instinct Leg Press/Calf Raise. $2,499.

Buying Considerations

  • Full calf development: program both standing and seated angles. The gastrocnemius and soleus respond to different knee positions.
  • Space-limited floors: a combo leg press/calf raise unit covers both stations without a dedicated calf machine.
  • High-turnover commercial floors: standing units are usually the higher-traffic default. Seated is a common second addition.
  • Budget planning: our standing unit (Premier Strength Beast Series, new, plate-loaded) starts at $1,599. Our seated unit (Cybex, refurbished, selectorized) starts at $995. Refurbished units cost less up front and still go through our inspection process.
  • New vs. refurbished: lower-impact than most lower-body machines, refurbished units hold up well. Every unit is inspected and tested before shipping.

Frequently Asked Questions

Standing vs. seated calf raise: what's the difference in muscle emphasis?

Standing calf raises (knee extended) emphasize the gastrocnemius, the larger outer calf muscle. Seated calf raises (knee flexed) shift emphasis to the soleus underneath it. Programming both angles covers the full calf.

Which calf raise machine builds a bigger calf: standing or seated?

For pure gastrocnemius size, standing wins. A 2023 training study found lateral gastrocnemius grew 12.4% on the standing leg versus 1.7% on the seated leg over 12 weeks, while the soleus grew about the same either way. If you can only stock one machine, make it standing. For full calf development, program both.

Do I need a dedicated calf raise machine, or can a leg press cover it?

Many leg press machines with a calf block, like our Star Trac Instinct combo, can double as a calf raise station, the more space-efficient choice for smaller floors. If you'd rather run a dedicated leg press without the calf add-on, see our full leg press machines lineup.

What's the difference between a plate-loaded and a selectorized calf raise machine?

Plate-loaded machines load with weight plates on a loading pin or horn. Selectorized machines use a pin-select weight stack. Our standing unit (Premier Strength Beast Series) is plate-loaded. Our seated unit (Cybex) is selectorized. Both work fine for commercial use; the choice usually comes down to whether your floor already stocks bumper plates or you'd rather members change loads with a pin.

How many calf raise machines does a commercial gym actually need?

Most general-purpose floors do fine with one standing unit as the default, since it drives more gastrocnemius growth per the research above and handles higher member turnover. Add a seated unit once member volume or program variety (physical therapy, bodybuilding-focused members, and similar) justifies a second station.

New or refurbished calf raise machine: does it matter?

This is a lower-impact equipment category than most lower-body machines, so a well-refurbished unit typically holds up just as well as new. Every unit is inspected and tested before shipping.

Do your calf raise machines come with a warranty?

Yes. Every new and refurbished machine we sell includes warranty coverage, and terms vary by condition. See our Warranty Information page for full details.
