I bought the Lever Arm Leg Press Attachment this past week as an upgrade to my X3 rack. I am strongly considering returning it now that I’ve seen how it integrates with the rack and only somewhat replicates certain exercise movements. Some of my observations: 1. Is it sturdy? Absolutely! Nearly 60 pounds of welded and powder-coated 1/4” steel and diamond plate. If Mad Max needed a new bumper for his truck, this would be it. There is no give in this piece. However, it is very awkward to hold in place and attach to the rack, largely because the design requires it to go between the rack’s vertical posts and the lever arms, meaning you have to move the arms and hold them out of the way, navigate the leg press inside them, and then hold it in place to insert the pins (which never align the first time). I can see some people having trouble doing this alone, or at all. The design would have been better if the diamond tread were on the inside, so that the leg press could be attached from the outside of the lever arms. 2. The dimensions of this piece should have been scaled down by 1/4” in width. It fits VERY tightly between the lever arms, or the vertical uprights of the rack (for wall ball twist throws), or between the spotter arms (for box jumps, step ups, etc.) This results in scratches and gouges in the powder coat of all pieces involved, and it makes installation significantly more challenging as you try to smack it into place. A slight margin of 1/8” on each side wouldn’t likely add wobble, but it would greatly improve the process of mounting it to the arms or rack. 3. The functionality is only so-so as a leg press. Most leg presses have a foot plate designed so that the user’s toes are slightly angled away from the user. This keeps the user’s heels in contact with the foot plate throughout the movement (see other Titan leg press machines and attachments). They also strive for a linear motion, not the dramatic arc that this attachment uses. This leg press attachment has a flat vertical foot plate with an overhead pivot, which means that as you press further, your heels are proportionally further away than your toes, which remain closer to the overhead pivot point. This means that the exercise is only a leg press in the early part of the movement, and then quickly becomes a calf raise / press. Therefore, the hamstrings, glutes, and quads receive little training effect, while the calves end up doing most of the work. 4. Related to the previous point, the overhead pivot point, arcing line of movement, and 6-o’clock vertical starting position of the foot plate mean that the weight attached to the lever arms is moving mostly horizontal at the beginning of the exercise, and only gains a vertical aspect as the exercise continues toward full leg extension. Like all other free weights, the resistance (and benefit) of this attachment relies on moving a weight against the influence of gravity. Pushing a weight horizontally is far easier than pushing it vertically (this is why most of us can push a car, but few of us could lift one). Since the influence of gravity only becomes a factor later in the movement when using this leg press attachment, and since at that point the calves are forced to do most of the work because of the design of this plate, there is little training benefit to the large muscle groups of the legs. 5. Because of the issues described in point #4, weight plates on the lever arms offer little benefit whatsoever with this leg press attachment. Really, the same is true with the lever arms in general (if you can bench 225 in a traditional position, you’ll be thrilled when you start chest pressing 300+ on the lever arms, because you’re not fighting gravity). The real way to use these tools is to attach heavy bands to the weight posts and either tie them off to the rack’s rear posts or attach them to band pegs. This will allow you to start the exercise under tension and work against resistance throughout the motion. I found that the banded exercises were no different with or without weight plates, and that changing resistance by adding or removing bands was far more effective. 6. I have a wood platform in the center of my rack, surrounded by rubber mats. Using a FID bench as my pressing chair, I found that I needed to use a chain with carabiners on each end running behind the front post of my bench to keep it from sliding backward when I pressed against the bands. 7. While Titan’s packaging and shipping have improved greatly in the past two years (which I can fairly judge after buying a lot of equipment!), this piece did arrive damaged. It looked like it had been dropped during transport, leaving one corner of the steel slightly dented and flattened with powder coating scraped off. It’s still functional , but it does add to the scratching on the rack or arms, and it’s just kind of ugly. BOTTOM LINE: I don’t see that the current design is so beneficial to my training that it’s worth the time or hassle to install this attachment. It takes up usable space on the rack, so you have to plan your workout accordingly so that you’re not wasting time attaching and removing the plate between exercises. Perhaps sitting outside the rack and pressing into it, instead of sitting inside the rack and pressing out, would leave space for working in the rack to superset leg presses. Also, there may be a way to attach the lever arm pivots low on the rack so that the handles are pointing up (upside down from the typical hanging method) and use bands so that as you press, your heels stay closer to the pivots than your toes do. This might change the exercise to better benefit your upper legs and glutes. Or you can just do any of the hundreds of other leg exercises that don’t rely on this heavy, awkward attachment. Long review, so thanks for your patience.
