<div><p>Tons of home workouts swear they’ll make you stronger, but not all of them are actually good at that job. If your heart is beating out of your chest and you’ve lost count of how many dozens of reps you’ve done, what you’re doing is probably <em>not</em> a good strength-training workout. </p><p>Most of those workouts just aren’t hard enough once you get past the beginner level. If you’re strong enough that you’d be squatting 100 (or 200 or 300) pounds in the gym, your muscles aren’t going to get much of a challenge from air squats, no matter how many of them you do. </p><p>Just as with <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://lifehacker.com/what-does-it-mean-to-lift-heavy-1846309501&quot;,{&quot;metric25&quot;:1}]]" href="https://lifehacker.com/what-does-it-mean-to-lift-heavy-1846309501" rel="noopener noreferrer" target="_blank">lifting heavy in the gym</a></span>, appropriately challenging bodyweight moves are  the ones that you can only sustain for a small number of reps, and require you to rest before your next set. So let’s look at some moves that actually fit the bill.</p><h2 id="h4682"><a id=""></a>Jackknife pullups</h2><p>In <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=0AGflL3itws&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=0AGflL3itws" rel="noopener noreferrer" target="_blank">this</a></span> alternative to  pullups, you put your feet up on a block or bench, and then do pullups (or chinups) as usual. It’s easier than a strict pullup, so you may be able to do these even if you can’t do real pullups. And if you <em>can</em> do a few real pullups, you’ll be able to do even more of these.</p><h2 id="h4683"><a id=""></a>Pike pushups</h2><p><span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=Ajna6AxQdtw&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=Ajna6AxQdtw" rel="noopener noreferrer" target="_blank">This move</a></span> is harder than a pushup but easier than a handstand pushup. By supporting the weight of your legs on the floor or a bench, you only need your arms to be strong enough to push up the weight of your torso. Make it harder by elevating your feet more and getting your torso upright; make it easier by bringing your feet down.</p><h2 id="h4684"><a id=""></a><strong>Shrimp squats</strong></h2><p>Squats get a lot harder when you take half your legs out of the equation. <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=_FBuC-VPbRY&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=_FBuC-VPbRY" rel="noopener noreferrer" target="_blank">Shrimp squats</a></span> are a variation where your free leg is held behind you. They’re harder when you hold your foot and touch your knee to the ground, and easier if you support your free foot lightly on the ground or on a bench or box. Check out the video above for more tips on how to do them.</p><h2 id="h4685"><a id=""></a><strong>Two-chair dips</strong></h2><p>Dips are a great exercise for your arms and chest, and ideally you’ll find a pair of parallel bars to do them on. (Many parks have a set as part of a fitness trail, or you might even luck out and find a well-situated set of railings.) If that’s not an option and you aren’t ready to invest in a pair of gymnastics rings or a freestanding dip station, there’s always <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=PNTB_BeqiMs&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=PNTB_BeqiMs" rel="noopener noreferrer" target="_blank">the two-chair dip</a></span>. Put each hand on one chairs, and lower yourself as far as you comfortably can between them, resting your feet on the ground if necessary. To make this move harder, put your hands on the backs of the chairs instead of the seats, or find some other tall surface like a pair of kitchen countertops.</p><h2 id="h4686"><a id=""></a>Step ups</h2><p>Here’s another squat alternative, and you can add weight to this one if you like. These <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=jcGbLEETLxs&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=jcGbLEETLxs" rel="noopener noreferrer" target="_blank">step-ups</a></span> are not the six-inch aerobics class kind. Get yourself a nice high box (or chair, bench, landscaping boulder, what have you) and step up on top of it and then back down. Make it easier by choosing a lower box; make it harder by slowing down the movement or grabbing a weight.</p><h2 id="h4687"><a id=""></a>Inverted rows</h2><p>Besides pullups, there aren’t many bodyweight exercises that work the biceps and lats. That means inverted rows are one of the most important elements of your bodyweight routine. You can do them on a bar (but again, a railing or something similar may work), or try <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=FKKZRwBJDxE&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=FKKZRwBJDxE" rel="noopener noreferrer" target="_blank">this version</a></span> that you can do under a sturdy table.</p><h2 id="h4688"><a id=""></a>Harop curls</h2><p>If your hamstrings are missing deadlifts, try <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=A2xRx7dGWaE&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=A2xRx7dGWaE" rel="noopener noreferrer" target="_blank">this bodyweight move</a></span>, which works some of the same muscles. The only thing you need is a place to anchor your feet—a partner can hold them down, or you can wedge your feet under a couch or belt them to a bench. The key feature of a harop curl is that you bend at the hips while  leaning forward. For a tougher version, check out the next slide.</p><h2 id="h4689"><a id=""></a>Nordic curls</h2><p>The notorious <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=v_Egn_3CCsM&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=v_Egn_3CCsM" rel="noopener noreferrer" target="_blank">Nordic curl</a></span> is a tough but effective exercise. As with pullups, you can work your way toward them using negatives or with bands—or do Harop curls until you’re ready to give this tougher variant a try.</p><h2 id="h4690"><a id=""></a>Reverse Nordic curls</h2><p>This move starts from the same position as a Nordic curl, but you <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=ayAqntt21eA&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=ayAqntt21eA" rel="noopener noreferrer" target="_blank">hinge your body backward instead of forward</a></span>, working your quads rather than your hamstrings. <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.strongerbyscience.com/reverse-nordic-curls/&quot;,{&quot;metric25&quot;:1}]]" href="https://www.strongerbyscience.com/reverse-nordic-curls/" rel="noopener noreferrer" target="_blank">Stronger by Science has a whole article</a></span> on why this move is great for your quads, but honestly it had me at “works the quads and isn’t a one legged squat.â€</p><h2 id="h4691"><a id=""></a>Copenhagen planks</h2><p><span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=CjinhqRzcaY&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=CjinhqRzcaY" rel="noopener noreferrer" target="_blank">Copenhagen planks</a></span> work your adductor (inner thigh) muscles as well as your core. Think of them as an extra spicy side plank. You can make them easier by doing them from your knee, or from a lower height, or by assisting a bit with your other leg.</p><h2 id="h4692"><a id=""></a>Negative pullups</h2><p>If you’re not satisfied with jackknife pullups, try the <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=EkpJkHpJXmM&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=EkpJkHpJXmM" rel="noopener noreferrer" target="_blank">negative version</a></span> of the regular kind. Slowly lowering yourself down to the ground will help to build the same muscles that pull you up. You can step off a box, as in this video, or just jump up to the top of the bar before lowering down.</p><h2 id="h4693"><a id=""></a>Ab rollouts</h2><p>The ab wheel is a wonderful thing, but you don’t actually need a wheel to do it. You can put your hands on gymnastic rings or a TRX style suspension trainer, or just do as in the video above and <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://www.youtube.com/watch?v=CR3CS7qhG_s&quot;,{&quot;metric25&quot;:1}]]" href="https://www.youtube.com/watch?v=CR3CS7qhG_s" rel="noopener noreferrer" target="_blank">place sliders under your hands</a></span>. You can buy sliders, or improvise them with whatever moves easily on your workout surface.
