{"product_id":"a400-deadlift","title":"Keiser A400 Deadlift","description":"\u003cp\u003eThe KEISER A400 Deadlift is a revolutionary pneumatic evolution of the trap-bar deadlift — using Pure Resistance Technology™ to remove the dangerous inertia of iron and enable athletes to train for explosive pulling power without the joint shock associated with heavy floor pulls. With Dynamic Variable Resistance that matches the body's natural strength curve, unilateral testing capability, and a 15.6\" touchscreen for velocity-based training, it is the most advanced deadlift machine available.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eZero-inertia lifting\u003c\/strong\u003e — no physical weight stack means no momentum at the top of the movement, enabling high-velocity concentric pulls that are impossible with traditional iron plates\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAscending strength curve (DVR)\u003c\/strong\u003e — Dynamic Variable Resistance provides less resistance at the bottom where you are mechanically weakest, increasing as you reach the top where you are strongest — perfectly matching the body's natural force curve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnilateral testing and training\u003c\/strong\u003e — each side can be trained and tested independently to identify and correct left-right strength imbalances; a feature unavailable on standard deadlift platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVelocity-Based Training (VBT) ready\u003c\/strong\u003e — the touchscreen tracks velocity for every rep, enabling coaches to identify sticking points and monitor speed loss — the critical indicator for set termination in VBT protocols\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety and joint protection\u003c\/strong\u003e — eliminates shock loading to the lower back and connective tissues, making it ideal for post-surgical rehabilitation and senior strength programmes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0–900 lb (0–409 kg) resistance range\u003c\/strong\u003e — from rehabilitation-level loads to elite power outputs, all with KEISER's characteristic smooth, zero-shock delivery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e683 lb (310 kg) frame\u003c\/strong\u003e — engineered for elite-level stability during maximum-velocity explosive pulls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 72\" H x 32\" W x 60\" L (1,829 x 813 x 1,524 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachine Weight:\u003c\/strong\u003e 683 lb (310 kg)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Range:\u003c\/strong\u003e 0–900 lb (0–409 kg)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance System:\u003c\/strong\u003e Pneumatic with Dynamic Variable Resistance (DVR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment:\u003c\/strong\u003e 1 lb \/ 1 kg increments via thumb buttons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement Type:\u003c\/strong\u003e Unilateral and bilateral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e 15.6\" colour touchscreen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetrics:\u003c\/strong\u003e Power, velocity, force, range of motion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectivity:\u003c\/strong\u003e Wi-Fi and Bluetooth\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eStocked at FSC Mayfair because the A400 Deadlift makes the most powerful posterior chain movement safer, more precise, and more data-intelligent than anything previously possible.\u003c\/em\u003e\u003c\/p\u003e","brand":"KEISER","offers":[{"title":"A400 Deadlift with A400 screen and compressor","offer_id":55994886914421,"sku":"003331","price":32246.4,"currency_code":"GBP","in_stock":true},{"title":"A400 Deadlift with A400 screen (NO COMPRESSOR)","offer_id":55994886947189,"sku":"003332","price":29037.6,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/4812\/1896\/files\/Keiser_A400_Deadlift.png?v=1758620436","url":"https:\/\/fscmayfair.com\/products\/a400-deadlift","provider":"FSC Mayfair","version":"1.0","type":"link"}
