Place your nails under a UV light for 1 minute to cure the primer. Since a UV light is the only way to truly cure the gel polish, you'll need to simply let the nails dry if you don't have the light. Let the nails dry for 25 to 30 minutes before applying another coat. If you like, you can finish with a top coat to protect the gel nails.

Summary: Cure your fingernails for 1 minute under a UV light. Dry the nails completely under UV light for 3 minutes between coats.


The oxygen sensors are small metal pieces attached to wires that connect into the sides of the exhaust pipe. Place a wrench around the bolt connecting the sensor to the pipe and rotate it counterclockwise until it’s loose. Pull the oxygen sensor straight out from the pipe before unplugging it from the wires connecting to your vehicle.  Your vehicle will usually have 1–2 oxygen sensors connected to the exhaust, but it may vary between make and model. Vehicles only have oxygen sensors if they have a catalytic converter. If your vehicle is from 1974 or prior, then the exhaust may not have oxygen sensors. Lie on a rolling creeper trolley to move around under your vehicle more easily. You can buy a creeper trolley from an automotive supply store. Wear clothes that you don’t mind getting dirty as well as disposable gloves so you don’t get too greasy. Penetrating fluid works between the bolt and nut threadings to add lubrication and make it easier to unscrew the system. Point the spout of the penetrating fluid directly at the nuts connecting the exhaust pipe to the downpipe attached to your engine. Make sure to coat all of the threadings evenly to make the job easier.  You can buy penetrating fluid from your local hardware or automotive care store. If you don’t have any penetrating fluid, it may be difficult to remove your exhaust system on your own. If your exhaust system is made up of multiple pieces, then look for bolts where the pieces connect to one another. Spray those with your penetrating fluid as well so you can remove each of the pieces separately. Start where your exhaust pipe connects to the engine at the front of your vehicle. Choose a ratchet bit that matches the size of the nuts holding the exhaust system to your vehicle. Place the end of the ratchet over the nut you’re loosening and turn it counterclockwise. Apply firm pressure as you rotate the nut since it may be stuck or locked in tightly. Continue unscrewing the rest of the nuts if the pieces of your exhaust system are held together by other bolts or clamps. Use a ratchet with a long handle so you can get more leverage while you’re disconnecting the old exhaust system. Look near the top of the pipe along its entire length to find the metal pins that extend up and into rubber rings on your vehicle’s body. Support the exhaust pipe with your nondominant hand as you slide the metal pin out from the rubber. Slowly and carefully take the other pins off so the exhaust system comes loose from the body of your vehicle.  If you have trouble pulling the metal pins off of the rings, try lubricating them with soapy water to help them slide out more easily. Don’t let the exhaust pipe drop since it could be heavy and it may hurt you or damage other components under your vehicle. Slowly take the exhaust system from the catalytic converter to the tailpipe and lower it to the ground. Carefully remove the system out from underneath the vehicle so it’s out of the way while you’re working. You can either throw the old exhaust system away or you can try to sell the parts if they’re in usable condition. Do not drive your vehicle while you have the exhaust system removed since it may be illegal in your area and you will release harmful fumes.

Summary: Disconnect the oxygen sensors from underneath your vehicle. Spray the nuts along the exhaust pipe with penetrating fluid. Unscrew the nuts with a ratchet. Unhook the pipes from the rubber exhaust hangers. Pull the exhaust system down from your vehicle.


In addition to cardio exercises, you can also include some strength training exercises using the stairs as well. Working your legs and glutes is particularly easy with stairs.  Lunges are an easy exercise to adapt to a staircase.  Lunges really work your legs and glutes without the addition of stairs, so doing them on stairs will really up the intensity.  To do lunges, you'll take the stairs two or three at a time.  Going for more stairs than this will increase your risk of overstraining. Step your right foot up two or three stairs.  Focus on pulling yourself up the stairs using your right leg.  You will notice this in your thigh muscles.  Push yourself up until your left leg comes to meet the right leg on the step. Repeat either on the same side or do alternating lunges.  Aim for 10 lunges per side or do as many as you're able. Running or jogging up the stairs is pretty taxing on your legs, glutes, heart, and lungs. If you want to get a balanced workout, you're going to want to include some upper body work as well. The elevation of the actual stairs also allows you to work the backs of the arms and triceps.  To start, face away from the staircase.  Rest your arms on the second or third stair with your fingers facing away from the stairs.  Grab the corner of the stair for this exercise and keep arms shoulder width apart. Keep your feet flat on the ground in front of you.  Press your hips up so that your arms are in a straight, extended position. Slowly lower your body down using your triceps to allow your body to dip down toward the stairs.  Lower down until your arms are bent about 90-degrees. Push yourself up back to the starting position. Try to do three sets of 15 to 20 reps. Like tricep dips, you can also use the stairs to do push-ups as well. These work your arms, chest and core muscles..  Start by facing the stairs and placing your hands on the first or second step.  Keep your legs extended behind you so you're almost in a plank-like position.  The higher the stair you use to place your hands, the easier this exercise is. While keeping your hands shoulder width apart, slowly bend your elbows so that your upper body and face slowly lower down towards the stairs. Lower down until your nose is almost touching the stairs.  Hold this position here for a few seconds and then slowly push yourself up to the starting position. Do a decline push-up variation by placing your feet on the bottom or second step and your hands on the floor at ground level. Similar to lunges, doing side steps up the staircase can help strengthen your legs, but more specifically the inner and outer muscles of your thighs.  Start this exercise by standing next to the stairs with your right shoulder facing the stairs. Step up 1 or 2 steps with your right leg and bring your left leg up to the step below it. Repeat until you get to the top and then do it again, this time leading with your left leg. This exercise can really make your calves pop. It works the gastrocnemius, which is likely what you think of when you imagine a calf muscle.  Start by standing on the edge of the stair. Only about the first fourth of each foot should be on the stair; your heels should be hanging off the edge. Rise up on your toes as high as you can. Keep your back, legs, and feet straight and don't allow yourself to lean forward or backwards. Slowly lower your body as far as possible. Keep one hand on the banister if balance is a concern.  Try doing this on one leg for an even more effective exercise, but only do so if you have a banister or wall to hold.
Summary: Try stair lunges. Do stair tricep dips. Use stairs to do push-ups. Try climbing side steps. Perform stair calf raises.
