David Kirsch Quotes

I do a lot of gym circuits; a bit like CrossFit or HIIT sessions, so just 20 seconds on, 10 seconds off. Circuits are a good fat-burner but they also work your heart and lungs.

I love doing air squats or jump squats, push-ups, jumping jacks, burpees, crunches - all the basic stuff, but it's all you need to do to keep it toned.

I like quick and efficient circuit training.

At times, I do Tabata, a high-intensity Japanese training regimen, in which I must do 20 seconds of a specific body part with 10 seconds of rest. This must be done eight times within four minutes. Your heart rate shoots through the roof, but you burn a lot of fat.

When I was first introduced to CrossFit, I found it to be the hardest workout that I'd ever done. It wiped the floor with me, and I fell in love with it immediately. The results that I have seen in my strength and physicality have been unparalleled to any other things I have ever done in my more than 20 years in the fitness business.

Working your core always, your foot speed, jumping rope, push-ups and sit-ups - things like that are really important. Those things will pay off more than just doing what a bench press will.

I'll get out and do Pilates. I'll get in the ring and do some rounds of kickboxing and grappling and MMA conditioning. There's a lot of unique stuff that I do, too, that a lot of people wouldn't imagine or think about doing, like box jumps. You get a 42-inch box and dumbbells and practice working on your explosion jumping up on those boxes.

The only constant that I have in my life is that I start whatever I do with my Total Gym, because I believe it helps keep me from getting injured.

I do a dance-based cardio workout infused with circuit training, and emphasizing strength and alignment.

Circuit training is a great way to go. Keeping the reps high and the weight low, you'll tone your muscles without bulking up.

I do a combo of running, weights, and core exercises and try to work out at least three times a week.

I work out every day - and my daily routine is a mix of functional and strength training.

Running hills, I try to follow the Jerry Rice routine.

I have to improve on my speed endurance, and I am working on it.

The programs I do with my trainer are amazing for overall strength and have a major focus on building my core. We do a lot of unique exercises that shake up the nervous system, which builds my balance and propreception. That's really important for my sport.

I like weightlifting and cardio workouts, and I'll do a lot of circuit workouts and plyometric as well.

I think CrossFit is highly beneficial to any athlete, in any sport.

People assume that you need to run fast to get to optimum fitness, but the truth is endurance lifting makes you stronger and leaner.

My fitness instructor helped me with strength training, muscle building, and toning.

We do a lot of lifting, and mix it up with upper body and lower body. A lot of circuit training for cardio. I hate just doing long distance running, so I do 5 or 6 different exercises for 20 to 30 seconds then move to the next one.

My only rule is to keep moving, for a pump and cardio at the same time. Rest as little as possible. After an hour, you will feel fantastic and your muscles won't know what hit them.

All the circuit training, it's cardio circuit training, so everything you're doing, you're still running up your heart rate. You're burning, I think, triple the amount of calories than if you were just weight lifting.

I don't think you should spend that much time in the gym. Don't sit around between sets too long. If you want to burn some calories, keep the sets tight. Give yourself 30 seconds to a minute between each set. Supersetting is brilliant.

Spin class is the best for your core!

When I was a teenager, I did a lot of pull-ups and push-ups. Every night before bed, I'd do 150 - in sets of 30 or so. Looking back on it now, I'm not totally sure that's the best way to improve as a climber. But it did make me a lot better at doing pull-ups and push-ups.
