High-volume interval training, or HIVT, on the other hand, is another effective way to train your body without the added strain. Unlike HIIT, which is supposed to be performed at your absolute max capacity at each interval, HVIT works your body at about 60-75 percent maximum effort, which means you can sustain it for longer.
If you're short on time and can't make it to the gym, personal trainer Corey Phelps, NASM, created this HVIT workout for POPSUGAR. This workout doesn't require any equipment — just your bodyweight.

The Spider-Man push-up variation will really challenge your upper body, work your core, and targets the muscles on the sides of the torso, too. There's no room for boredom to creep into your workout when doing this push-up!
Start in a traditional plank position, with your hands under your shoulders, and your body in one straight line.
Bend your elbows out to the side to lower your torso toward the floor, bring your left knee and touch it to your left elbow.
As you straighten your arms, return to plank position bringing your left foot next to your right; then repeat this move on the other side. This counts as one rep.

Lower into a crouching squat with your hands on the floor.
Do a squat thrust by jumping your feet back into a plank position.
Do one basic push-up, bending the elbows and then straightening back to plank.
Jump the feet forward to the hands, and come into a squat.
Do an explosive jump straight up, getting as much height as you can.

Sumo Squat

Taking your legs out wide for this squat variation will make you feel it more in your inner thighs.
Stand with your feet wide, toes pointing out. Bend your knees, lowering your hips deeply, so your thighs are parallel with the floor. Make sure to keep your weight back in your heels.
Then rise back up, straightening the legs completely and squeezing the glutes at the top of the movement to get the most from the exercise.
It's one of those retro gym moves that gets the job done! Tone the backs of your arms with classic triceps dips.
Position your hands shoulder width apart on the floor or on a secured bench or stable chair.
Move your booty in front of the bench with your legs out in front of you and feet placed about hip width apart on the floor.
Straighten your arms, and keep a little bend in your elbows in order to always keep tension on your triceps and off your elbow joints.
Now slowly bend at your elbows, and lower your upper body toward the floor until your arms are at about a 90-degree angle. Be sure to keep your back close to the bench.
Once you reach the bottom of the movement, slowly press off with your hands, and push yourself straight back up to the starting position.
This counts as one rep.
